Et accusabant eum summi sacerdotes in multis. Pilatus autem rursum interrogavit eum, dicens: Non respondes quidquam? Vide in quantis te accusant. Iesus autem amplius nihil respondit, ita ut miraretur Pilatus. (Mk 15.3-5)
And the high priests accused him of many charges. Pilate, moreover, asked him again, saying: “Why do you not answer? See how many charges they are accusing you of.” But Jesus all the more said nothing, and at this Pilate was astonished. (Translation mine)
Humans are given the remarkable gift of speech, reflecting that Trinitarian relationship between God the Father and the Word who proceeds. Because of this gift, we as God’s creatures are compeled to return the gift of speech back to our Creator, to render praise to Him who has given us the gift of speech.
Otherwise, we are to remain silent, lest we fall into sin.
