The Ascetical Homilies of St. Isaac the Syrian - Homily XV, Part III

At first reading, Isaac’s words can sound severe, even shocking. He speaks of idle speech as fornication, unhealthy attachments as adultery, and certain forms of companionship as idolatry. Yet behind these warnings lies something far deeper than moral anxiety. Isaac is not obsessed with sin. He is consumed with the preservation of desire for God.

The entire homily is built upon a single conviction: the human heart was created for divine communion, and anything that captures its attention, dissipates its energy, or redirects its longing away from God becomes a threat to its deepest purpose.

For Isaac, impurity begins long before outward acts. It begins when the heart loses its simplicity. When affection becomes possessive, when companionship becomes emotionally intoxicating, when curiosity about others replaces watchfulness over oneself, the soul gradually drifts from its center. The danger is not merely moral failure. The danger is fragmentation.

This is why Isaac speaks so strongly about particular attachments and associations. He understands that the heart cannot be divided indefinitely. Every affection shapes desire. Every conversation leaves a trace. Every companionship either strengthens recollection of God or weakens it.

His concern is especially acute regarding spiritual relationships because these can easily disguise passion beneath the appearance of virtue. A person may speak about holiness while secretly seeking emotional gratification, admiration, dependence, or control. One may appear spiritual while feeding hidden desires. This is why Isaac repeatedly returns to self-deception. The greatest danger is not obvious sin but the passions clothed in religious garments.

Against this, Isaac presents another image: the elder who has guarded his heart through silence, purity of thought, humility, and disciplined speech. Such a person no longer seeks particular people to satisfy hidden needs. He loves everyone equally because his heart has become free. Compassion has replaced possession. Love has become universal because it no longer springs from lack.

This is the perfection Isaac describes.

The issue, then, is not whether one has relationships. It is whether one’s relationships nourish the fire of God or extinguish it.

For Isaac, solitude is not an end in itself. Silence is not a technique. Withdrawal is not misanthropy. All of these exist to protect a flame. The Holy Spirit has kindled a fire within the heart, and that fire is delicate. Excessive familiarity, endless conversation, emotional entanglements, and worldly distractions scatter the mind and cool the soul.

Yet Isaac is careful to make one exception.

There are companions who do not extinguish the fire but increase it. There are friendships rooted in God. There are conversations that awaken the soul, expose the passions, deepen humility, and enlarge desire for divine things. Such communion is not a distraction from the spiritual life but one of its greatest supports.

The test is simple: after leaving someone’s company, does the heart burn more brightly for God or less?

Everything in this passage revolves around that question.

Isaac’s warnings are not expressions of fear. They are acts of protection. He sees the heart as a sanctuary and desire for God as its most precious treasure. Therefore he urges vigilance, not because human relationships are evil, but because divine love is so extraordinarily precious.

The entire passage can be reduced to a single plea:

Guard the fire.

Choose companions who increase it.

Flee whatever diminishes it.

And allow your love to become so purified that it belongs to everyone because it belongs first to God.

00:16:54 Bob Čihák, AZ: P 206, #11, last paragraph, Fr. A said we should get back to the 2nd sentence.

00:31:04 James Hickman: “…his heart is grievously injured.” Is Isaac speaking of the older monk, ie the one at fault? If so, I like Isaac’s compassion to warn against the danger the offended faces. We don’t want anyone’s heart injured, whether a potential offender or a potential victim.

00:37:51 Bob Čihák, AZ: The double negative in the last sentence of the paragraph tends to confuse my weakening mind.

00:42:37 David Swiderski, WI: It is interesting the human brain only matures after 25 years old. I think most parents can capture this as the entire idea of consequences does not develop till after that. That is why around the world to rent a car you need to be 25. I see people below this age as children still developing but I see others that year to live again in a world without consequences.

00:43:05 Anna: Too often we run to therapy versus running to Christ in prayer and confession

00:44:03 una: Can you speak to how to have a solid spiritual friendship between consecrated people or with priests/monks

00:48:49 David Swiderski, WI: On the scandals the biggest problem is public teachers almost weekly here in the Midwest we hear of this and strangely most of the ones in my area have been women even married. In fact during my sons time in high school there were 3 abuse cases in the school system. A dear Jewish family we knew actually moved their sons to Catholic schools because at least there are safety measures in place. When I did catechism I had to take 6 months of courses and background checks which I think was great.

00:49:45 Anna: Protestors are hidden and manipulative because Satan helps keep things in the dark.

00:59:59 Rebecca Thérèse: The anti-psychiatry psychiatrist, Thomas Szasz, wrote an article "Sins of the Fathers", about how the psychologising of criminal behaviour had led to the redeployment of abusive clergy leaving them free to re-abuse. This would not have happened without the psychologising of the Church and its attitude to doctrine and ethics :https://reason.com/2002/08/01/sins-of-the-fathers-2/

01:07:46 Anna: Sorry I meant predictors in church are manipulative and hidden

01:08:27 David Swiderski, WI: The church is held to a divine standard while Chesterton was attracted  to the one who stole his umbrella. If even the worse can be there that is the place for me a sinner.

01:09:30 Eleana Urrego: I usually said to my patients that the role of a therapist is a tool, like a compás, to help you find your “Path,” Or the “Truth,” or the “Life,” if they are atheists, because the reality is that Christ is the Divine Healer—after all, the evil plant his seed in pain where pride and fear grow.

01:09:30 Ben: You talked about all of us enduring these conditions like loneliness, etc. And I want to add, even I, in the midst of a large, loving, family, with a loving and attentive husband.  experience loneliness, my message is that, that is because we were all created with a God sized hole in our hearts and only God will fill us.
