Homily - From Doubt to Communion: What It Means to Believe in Christ

This homily reflects on belief as trust that creates communion and makes true life possible in Christ. Drawing on the encounter with Thomas, it shows how Christ patiently leads honest doubt into faith while calling us away from prideful questioning that blocks love.

St. Thomas Sunday
St. John 20:19–31

Does God hate doubt? Does He shame those who struggle to believe? No. He does something very different.

Christ does not simply want us to know facts about Him. He wants us to know Him. Because He does not say, “I teach the truth.” He says: “I am the Truth” (cf. Gospel of John 14:6). This changes everything. Belief is not first about ideas—it is about relationship.

And yet, God does not want us to remain in doubt. He does not want us to be uncertain about His love, His power, or His promise to save us. Because, as He says elsewhere, “Whoever believes in Me shall never die” (cf. John 11:26). Belief is not optional. It is the doorway into life. But notice how He brings people to belief. He does not force it. He does not shame it into existence. He draws it out—patiently, personally, just as He did with Thomas.

So what does it mean to believe in someone? It means you trust them. You trust their intentions, their character, and their power to do what they say. We understand this instinctively. In a healthy marriage, a husband believes in his wife, and a wife in her husband. In a healthy home, children believe in their parents—not because they have proven every detail, but because they have learned to trust who they are.

And when that kind of belief is present, something happens. There is freedom. A husband does not second-guess every word his wife says. A wife does not interpret every silence as betrayal. They are free to give themselves to one another without fear. There is peace. The home is not filled with suspicion or quiet anxiety, but with a steady confidence that they are for one another. There is growth. Because when you are not constantly defending yourself, you can repent, forgive, and become better. And there is joy—not because everything or anyone is perfect, but because love can actually be received and returned.

This is what belief does. It creates the conditions where life—real life—can exist.

And when that belief is gone, the relationship begins to collapse. If a spouse becomes convinced the other is unfaithful, the mind will begin to manufacture evidence to support that fear. Everything changes: suspicion replaces trust, distance replaces unity, and anxiety replaces peace. Without belief, there is no communion—no harmony, no shared life. And where communion is lost, what remains begins to resemble hell: isolation, suspicion, and the slow unraveling of love.

Christ has come to trample down that isolation and to bestow life. Trust and belief are how we share in that victory.

This is what makes today’s Gospel so important. Christ is worthy of our trust. His intentions toward us are not hidden: He loves us and desires that we share eternal life with Him. His power is not uncertain: He has risen from the dead. And He has not left us empty-handed. He gives us Himself—His Body and His Blood—so that this trust is not abstract, but lived, received, and renewed.

You have already begun this. You have united yourself to Christ. You believe in His love, and you have accepted it as your own. You believe in His power, and you are learning to live in it.

But the fallen mind will still produce doubts. That is what the fallen mind—especially the intellect—does. It generates possibilities, questions, fears. And that is not, by itself, a problem.

Do not be afraid of your doubts. In any real relationship, questions must be brought into the light—not during the Liturgy, but within the life of the Church, within this community, where truth can be sought in humility and trust. You are not the first to ask hard questions. Some of the greatest minds and the greatest saints have wrestled with them.

If your questions come from love—from a genuine desire to know God—then working through them becomes a holy act. Because honest dialogue leads to deeper communion. Not every thought needs to be followed—only the ones that lead us toward Christ.

And this leads us to another kind of questioning—a kind that works against the asker’s salvation. Questions that come from pride, from mockery, from a desire not to know but to dismiss. “I’m only asking questions.” But pride blocks the way to truth. Because the problem of our salvation is not lack of information—it is a prideful and poisoned heart. And no amount of facts can heal that. Only repentance can.

And Christ shows us one more thing. He is patient with doubters like Thomas, but He is not patient with those who “believe” in the wrong way—those who cling so tightly to false beliefs that they harm others in the name of God. The Pharisees were not condemned because they questioned, but because they refused to be corrected. And even more, because they refused communion. Their questions were designed to show their own righteousness and served as a barrier to communion—a barrier to love.

So what are we to do?

Believe. Not harshly. Not defensively. Not with fear. But gently, patiently, and with love.

Trust Christ—His love for you, His power to save you, and His promise to give you life. And bring your questions to Him honestly. Because He is not afraid of them. He will meet you in them. And He will lead you—from doubt, into trust, and from trust, into life.
