Caesarius of Arles : Let us not deceive ourselves with a false security, believing that a nonresponsive faith lacking good works can deliver us against the day of judgment. — SERMON 209.3 Cosmas Indicopleustes : For the kingdom of God is not in word but in power; as if he said that the word of the kingdom of heaven surpasses all words, and that some are in vain puffed up while endeavouring to establish themselves by word. For that word only, which comes from the power of the Holy Spirit and from the signs which accompany it, merits belief. — The Christian Topography, Book 7 Cyprian : That we must labour not with words, but with deeds. In Solomon, in Ecclesiasticus: "Be not hasty in thy tongue, and in thy deeds useless and remiss." And Paul, in the first to the Corinthians: "The kingdom of God is not in word, but in power." Also to the Romans: "Not the hearers of the law are righteous before God, but the doers of the law shall be justified." Also in the Gospel according to Matthew: "He who shall do and teach so, shall be called greatest in the kingdom of heaven." Also in the same place: "Every one who heareth my words, and doeth them, I will liken him to a wise man who built his house upon a rock. The rain descended, the floods came, the winds blew, and beat upon that house, and it fell not: for it was founded upon a rock. And every one who heareth my words, and doeth them not, I will liken him to the foolish man, who built his house upon the sand. The rain descended, the floods came, the winds blew, and beat upon that house; and it fell: and its ruin became great." — Treatise XII Three Books of Testimonies Against the Jews John Chrysostom : "For the kingdom of God is not in word, but in power." By signs, saith he, not by fine speaking, we have prevailed: and that our teaching is divine and really announces the Kingdom of Heaven we give the greater proof, namely, our signs which we work by the power of the Spirit. If those who are now puffed up desire to be some great ones; as soon as I am come, let them shew whether they have any such power. And let me not find them sheltering themselves behind a pomp of words: for that kind of art is nothing to us. — Homily on 1 Corinthians 14 Origen of Alexandria : It is not smooth talk that reveals the presence of the kingdom of God, but power. When there is power in the words, then the kingdom is present in them. — COMMENTARY ON 1 CORINTHIANS 2.22.6-8 Theodoret of Cyrus : It is not enough to preach the kingdom of God in order to be saved; one must also behave in a way which is worthy of the kingdom. — COMMENTARY ON THE FIRST EPISTLE TO THE CORINTHIANS 191
