~ The Incarnation

Your senses and your words are powerless to account for it; the fact is certain, but it lies beyond the region of human explanation. If, as you say, our account of the Divine birth is a lie, then prove that this account of tile Lord's entrance is a fiction. If we assume that an event did not happen, because we cannot discover how it was done, we make the limits of our understanding into the limits of reality. But the certainty of the evidence proves the falsehood of our contradiction. The Lord did stand in a closed house in the midst of the disciples; the Son was born of the Father. Deny not that He stood, because your puny wits cannot ascertain how He came there; renounce a disbelief in God the Only-begotten and perfect Son of God the Unbegotten and perfect Father, which is based only on the incapacity of sense and speech to comprehend the transcendent miracle of that birth.

~ The Incarnation

The Lord stoops to the level even of our feeble understanding; to satisfy the doubts of unbelieving minds He works a miracle of His invisible power. Do you, my critic of the ways of heaven, explain His action if you can. The disciples were in a closed room; they had met and held their assembly in secret since the Passion of the Lord. The Lord presents Himself to strengthen the faith of Thomas by meeting his challenge; He gives him His Body to feel, His wounds to handle.
