The Secret to Defeat Satan’s Greatest Weapons

Father Isaac was interviewed recently by John-Henry Weston; in this interview Father pulls no punches in this unflinching interview on the spiritual mechanics of sin and the path to real freedom. With arresting clarity, he exposes what too often goes unnamed: mortal sin is not merely weakness, it is a deliberate act of telling God, “Get out. I don’t want You.”

He warns against treating confession as a revolving door while continuing the same behavior without amendment, and he dismantles the culture of blame that externalizes sin onto the devil, trauma, or society. “Stop blaming the devil for what you’re choosing,” he insists, calling men especially to accountability, discipline, and decisive action. The message is urgent, pastoral, and uncompromising: God’s mercy is real, but it is not sentimental. Grace demands cooperation, and freedom requires the courage to face oneself first.

Why Marian Doctrine Matters

[Direct link to the MP3 file — Subscribe using a modern podcast app]

In this sermon Father discusses the Catholic doctrine that the Blessed Virgin Mary is rightly called Co-Redemptrix and Mediatrix of all Graces, that these titles belong to the deposit of faith and are consistently taught by Scripture, Tradition, the Fathers, Doctors, Saints, and Popes. Denying these Marian titles undermines authentic Christology, rejects the Church’s historical teaching authority, and results in doctrinal collapse masked by false ecumenism. We need unwavering devotion to Our Lady, especially in the present age of crisis, presenting her as God’s chosen instrument for the final victory over error and the salvation of souls.

Key quotes from this sermon:

St. Louis de Montfort: “God wishes to make Mary better known in the latter times.”
St. Alphonse Liguori: “If you call on Our Lady promptly in temptation, it is an infallible sign that you will not fall.”
St. Maximilian Kolbe: “Mary is Co-Redemptrix because she is the Immaculate Conception, uniquely united to the Holy Ghost.”
St. Vincent of Lérins: “We must hold what has been believed everywhere, always, and by all.”
St. Jerome: “The whole world groaned and was astonished to find itself Arian.”
St. John Eudes: “All the Fathers of the Church clearly teach that Mary is Co-Redemptrix with Christ in the work of salvation.”

The Assumption of Mary: Triumph of Love

[Direct link to the MP3 file — Subscribe using a modern podcast app]

In this sermon Father discusses the dogma of the Assumption of the Blessed Virgin Mary as defined by Pope Pius XII, emphasizing the Church’s infallible authority to proclaim divinely revealed truths and the necessity of assenting to every dogma of the Catholic faith. Mary’s Assumption is inseparable from her perfect detachment from sin and the world, her total conformity to the will of God, and her unique participation in Christ’s redemptive work through love, suffering, and humility. Let us imitate Mary and the saints by practicing detachment, living sacramentally, preparing daily for death, and trusting in Our Lady’s powerful intercession for perseverance and salvation.

Key quotes from this sermon:

St. Thomas Aquinas: “To reject one dogma is to reject them all.”
St. Robert Bellarmine: The Art of Dying Well — “To die well, one must first die to the world.”
St. Bernard of Clairvaux: “Blessed is that death which is purchased at any price.”
St. Francis of Assisi: “My God and my all.”
St. John of the Cross: “One may be attached even to something holy, such as a rosary.”
St. Augustine of Hippo: “Before sin, the devil tells you God is merciful; after sin, he tells you God will never forgive.”
St. Alphonsus Liguori: “As you live, so you will die.”
St. John Vianney: Assurance given to Augustine Cohen regarding his mother’s salvation through Marian intercession.
St. Bernardine of Siena: Christ Himself went forth to meet His Mother at her Assumption.
St. Anselm of Canterbury: Christ ascended first in order to prepare and accompany Mary to her heavenly throne.
St. Peter Damian: The Assumption of Mary surpasses even the Ascension in splendor.
St. John Damascene: Christ Himself gave Mary Holy Viaticum before her Dormition.

The Woman, the Serpent, and the Triumph of the Immaculate Heart

[Direct link to the MP3 file — Subscribe using a modern podcast app]

In this sermon Father discusses the divine motherhood of the Blessed Virgin Mary as the foundation of all Marian doctrine and as inseparable from authentic Christology and the Catholic Faith. Attacks on Mary’s titles — especially Mother of God, Mediatrix of all Graces, and Co-Redemptrix — are signs of doctrinal collapse foretold by saints, councils, and Marian apparitions. Heresy against Mary inevitably leads to heresy against Christ; we need to remain steadfast, to defend revealed dogma even amid ecclesial confusion, and to deepen devotion to Our Lady — particularly through the Rosary — as a sign of fidelity and perseverance unto salvation.

Key quotes from this sermon:

St. Louis de Montfort: “Whoever wishes to possess Jesus must possess Mary.”
St. Alphonse Liguori: “One good priest leads thousands to heaven; one bad priest leads thousands to hell.”
St. Louis de Montfort: “Jesus is the fruit of Mary, and Mary is the true tree of life.”
St. Justin Martyr: “The Virgin Mary became the cause of salvation for herself and for the whole human race.”
St. Irenaeus of Lyons: “The knot of Eve’s disobedience was loosed by the obedience of Mary.”
St. Augustine: “The elect are carried in the womb of Mary until she brings them forth into eternal glory.”
St. Catherine of Siena: “This vice [sodomy] is so abominable that even the demons turn away in horror.”

The Immaculate Conception: Dogma, Defense, and Devotion

[Direct link to the MP3 file — Subscribe using a modern podcast app]

In this sermon Father discusses the Immaculate Conception, explaining how Blessed Duns Scotus resolved theological difficulties by arguing that it was fitting for God to preserve His mother from original sin, a doctrine later defined as dogma by Pope Pius 9th. Mary is the “woman” of Genesis who crushes the serpent’s head, and as the “mold of God,” she serves as the perfect mediator to help the faithful be transformed into Christ. We need to practice total consecration to the Immaculate, imitating her virtues and relying on her intercession as it is the surest path to salvation and victory in spiritual warfare.

Key quotes from this sermon:

St. Augustine: “Mary was the only one who merited to be called the mother and spouse of God.”
St. Augustine: “For sin never had any entry into the soul of the Blessed Virgin.”
St. Bernard of Clairvaux: “Thou alone was found worthy to be chosen as the one in whose virginal womb the king of kings should have his first abode.”
St. Bernard of Clairvaux: “Noah’s ark was a type of Mary, for as by its means men were preserved from the deluge, so are we all preserved by Mary from the shipwreck of sin.”
St. Bonaventure: “It was becoming that the Blessed Virgin Mary by whom our shame was to be blotted out and by whom the devil was to be conquered should never even for a moment have been under her dominion.”
St. Thomas Aquinas: “It was necessary that he, Christ, who was to take away sin, should be separated from sin as to the fault under which Adam lay.”
St. Ambrose: “Christ chose this vessel unto which he was about to descend not avert but from heaven and he consecrated it a temple of purity.”
St. Louis de Montfort: “I still would choose the immaculate way of Mary. It is a way a road without stain or spot without original sin or actual sin without shadow or darkness.”
St. Louis de Montfort: “Mary is the great mold of God fashioned by the Holy Ghost to give human nature to a man who is God… and to fashion through the grace men who are like to God.”
St. John Damascene: “O Blessed Virgin, thou was born and thou mightiest minister to the salvation of the whole world.”

Soldiers of the Immaculate with Fr. Isaac: [Lenten Mission] Heaven: Our True Home and Highest Goal

[Direct link to the MP3 file — Subscribe using a modern podcast app]

We were made for Heaven, and we must live with our eyes fixed firmly on that glorious reward. Don’t aim merely for purgatory—shoot for Heaven, for if you aim low and miss, hell awaits. Let nothing distract you from your eternal end. In Heaven, there will be no sickness, no suffering, no fear, no sin—only love, peace, and the beatific vision. Meditate on it often, speak of it with joy, and long for it with all your being! Unite your daily crosses to Christ’s Passion, cling to our Blessed Mother, frequent the sacraments, especially confession and Holy Communion, and strive for virtue. Remember, your glory in Heaven depends on your love for God here and now. So run the race well, carry your cross with joy, and bring souls with you—for no one goes to Heaven or hell alone.

Quotes from the Saints:

St. Maximilian Kolbe – “Aim higher.”
St. Francis de Sales – “Never speak or act when you’re angry.”
St. Paul – Multiple references from his epistles and his sufferings.
St. Bernard – “Do you wish to know what heaven is? There is nothing there that gives pleasure. There is everything that delights.”
St. Augustine – “He who sings well, prays twice.”
St. Alphonse (de Liguori) – Multiple quotes and references, including stories from Preparation for Death.
St. Bonaventure – “What measure men put into their love of God here will be the measure of their rejoicing in God in heaven…”
St. John of the Cross – Mentioned with admiration for his suffering and love of the cross.
St. Pio (Padre Pio) – “The more you are afflicted, the more you should exalt… a soul in the fire of tribulation will become refined gold…”

Soldiers of the Immaculate with Fr. Isaac: [Lenten Mission] The Rosary: Heaven’s Weapon for These End Times

[Direct link to the MP3 file — Subscribe using a modern podcast app]

In these dark and perilous times, when sin abounds and the world seems overtaken by evil, we must remember that where sin increases, grace abounds all the more. God, in His mercy, has given us a mighty weapon for these days: the Holy Rosary. After the Holy Sacrifice of the Mass, it is our greatest spiritual aid. Do not underestimate its power. Our Lady herself, from Fatima to Lourdes to Akita, has pleaded with us: “Pray the Rosary every day.” Through this prayer, peace is brought to the world, the Church is defended, our families are protected, and our souls are saved. It is through the Rosary that we meditate on the life of Christ, grow in virtue, and resist temptation. So I urge you, pray the Rosary: not with mere lips, but with heart and mind united. Pray it daily, faithfully, and reverently. Make it the heartbeat of your home and the weapon you carry into battle. Heaven is watching. The Queen of Heaven is calling. Will you respond?

Quotes from the Saints:

Our Lady to Lucia (Fatima): “Say the Rosary every day to bring peace to the world and the end of the war.”
St. Bernard: “I cannot promise you happiness in this world, only suffering, but you will have great happiness in the next.”
Our Lady to St. Dominic: “From this day, you will speak about nothing and preach about nothing but the Hail Mary.”
St. Louis de Montfort: “In the end times, God will raise up little ones who will do greater works than the apostles.”
St. Louis de Montfort (on the Rosary): “If you have one foot in hell and you call upon Our Lady, she will yank you out.”
St. Louis de Montfort: “A single Hail Mary said properly is worth more than 150 said badly.”
St. Pio: “Pick up your weapon!!!” (Referring to the Rosary)
Fr. Patrick Peyton: “The family that prays together stays together.”
St. Alphonsus: “If you call upon Our Lady immediately during temptation, especially of impurity, you will not fall.”
St. John Vianney (related through the story of Fr. Augustine Cohen): “You will receive a letter on the Feast of the Immaculate Conception that will bring you joy.”
Blessed Alan de la Roche: “The Rosary brings countless blessings…”
St. John Eudes: “The worst punishment from God is wicked prelates and priests.”

Soldiers of the Immaculate with Fr. Isaac: [Lenten Mission] The Seven Capital Sins

[Direct link to the MP3 file — Subscribe using a modern podcast app]

During this holy season of Lent, the most crucial step in your spiritual journey is to truly know yourself—to identify your sins and weaknesses, especially that one prominent vice that acts like a stubborn weed in the garden of your soul. Don’t get overwhelmed by your many defects; pinpoint that main root, whether it’s pride putting yourself first, avarice clinging to earthly goods, or another capital sin. Then, focus your fight! The remedy isn’t just willpower; it’s embracing the opposite virtue, like humility against pride or generosity against avarice. Look to Christ, His Holy Mother, and the saints as your models, imitate their humility and detachment, accept the humiliations God sends to purify you, and remember that without God, you can do nothing. Rip up that root vice by its source, and all other virtues will begin to flourish within you.

Soldiers of the Immaculate with Fr. Isaac: [Lenten Mission] The Fires of Divine Justice: Understanding and Assisting Souls in Purgatory

[Direct link to the MP3 file — Subscribe using a modern podcast app]

Purgatory is REAL and SEVERE! It is a place where souls in a state of Grace, but not yet fully purified, undergo intense suffering to atone for their sins. It is important to offer prayers and Masses for the Poor Souls, especially Gregorian Masses, and acts of Charity for the relief of these souls. Purgatory is a manifestation of God’s Justice and His Mercy. We need to strive for holiness in this life to avoid the suffering of purgatory and to assist the holy souls through spiritual works of mercy.

Books recommended in this Mission Sermon:

Citations mentioned in this Mission Sermon:

Saint Augustine: “It cannot be doubted that the prayers of the Church, the Holy Sacrifice, and alms distributed for the departed relieve those holy souls.”
Saint Bonaventure: “Ponder in mind on the joy of heaven… let your soul hunger and your body thirst for it.”
Saint Catherine of Genoa: “How terrible are those expiatory pains since they have caused me to mistake minutes for a year.”
Saint Gregory: “The same fire torments the damned and purifies the elect.”
Saint Monica (to Saint Augustine): “The one thing I ask of you is that you will be mindful of me at the altar of the Lord.”
Saint Anthony Mary Claret: “The souls in hell are like fish in water, but they are in fire—consumed by it.”
