Theophylact of Ohrid, on Rom 16:20

“And the God of peace crush Satan under your feet speedily. The grace of our Lord Jesus Christ be with you.”

“Since there were disputes, he calls upon the Giver of peace to put an end to the divisions. He does not say "will subdue," but what is much stronger: "will crush," and will crush not only those who introduce divisions, but also their leader. He also offers comfort regarding the timing, for he added: shortly. The word "will crush" expresses both a prayer and a prophecy, because it stands in the future tense. He also reminded them of grace, so that, judging by what they had already received, they would become more zealous in believing with regard to the future as well; for if the Lord saved them at the time when they were enemies, how much more will He now crush Satan. Notice, then: the apostle separates neither deeds from prayer, nor prayer from deeds. First he testified of their obedience, and then he began to pray, by which he made it known that not only before, but also now, even if we are skilled, we have need of the grace of God.”
