GREGORY . (ubi sup.) But what should we consider in these words, if it be not that obedience follows the precept and signs follow the obedience? For the Lord had commanded them, Go into all the world preaching the Gospel, and, Ye shall be witnesses even unto the ends of the earth.
AUGUSTINE . (Epist. cxcix. 12.) (Acts 1:8) But how was this preaching fulfilled by the Apostles, since there are many nations in which it has just begun, and others in which it has not yet begun to be fulfilled? Truly then this precept was not so laid upon the Apostles by our Lord, as though they alone to whom He then spoke were to fulfil so great a charge; in the same way as He says, Behold, I am with you always, even unto the end of the world, apparently to them alone; but who does not understand that the promise is made to the Catholic Church, which though some are dying, others are born, shall be here unto the end of the world?
THEOPHYLACT . But we must also know from this that words are confirmed by deeds as then in the Apostles works confirmed their words, for signs followed. Grant then, O Christ, that the good words which we speak may be confirmed by works and deeds, so that at the last, Thou working with us in word and in deed, we may be perfect, for Thine as is fitting is the glory both of word and deed. Amen.
