Ignatius — Epistle to the Ephesians 13
So make every effort to meet more often to give thanks to God and to give him glory. When you gather often, Satan's powers are torn down, and the ruin he works comes apart in the oneness of your faith.
Nothing is better than peace. In peace every war of heavenly beings and earthly beings is abolished.
Greek
Σπουδάζετε οὖν πυκνότερον συνέρχεσθαι εἰς εὐχαριστίαν θεοῦ καὶ εἰς δόξαν. ὅταν γὰρ πυκνῶς ἐπὶ τὸ αὐτὸ γίνεσθε, καθαιροῦνται αἱ δυνάμεις τοῦ Σατανᾶ, καὶ λύεται ὁ ὄλεθρος αὐτοῦ ἐν τῇ ὁμονοίᾳ ὑμῶν τῆς πίστεως.
οὐδέν ἐστιν ἄμεινον εἰρήνης, ἐν ᾗ πᾶς πόλεμος καταργεῖται ἐπουρανίων καὶ ἐπιγείων.
