"It is better for a man to be silent and be [a Christian], than to talk and not to be one."
"It is better for a man to be silent and be [a Christian], than to talk and not to be one. It is good to teach, if he who speaks also acts. There is then one Teacher, who spake and it was done; while even those things which He did in silence are worthy of the Father. He who possesses the word of Jesus, is truly able to hear even His very silence, that he may be perfect, and may both act as he speaks, and be recognised by his silence." (Ignatius, Epistle to the Ephesians, short version, ANF I, ch. XV, p. 93)
