Ignatius to the Ephesians

It is better to keep silence and to be, than to talk and not to be. It is a fine thing to teach, if the speaker practice. Now there is one teacher, who spake and it came to pass: yea and even the things which He hath done in silence are worthy of the Father.

Ἄμεινόν ἐστιν σιωπᾶν καὶ εἶναι, ἦ λαλοῦντα μὴ εἶναι. καλὸν τὸ διδάσκειν, ἐὰν ὁ λέγων ποιῇ. εἶς οὖν διδάσκαλος, ὃς εἶπεν, καὶ ἐγένετο: καὶ ἃ σιγῶν δὲ πεποίηκεν ἄξια τοῦ πατρός ἐστιν.

He that truly possesseth the word of Jesus is able also to hearken unto His silence, that he may be perfect; that through his speech he may act and through his silence he may be known.
