“Therefore let us follow after the things that are of peace; and keep the things that are of edification one towards another.”
“This applies to the other, that he may grow peaceable. But the other to the latter too, that he may not destroy his brother. Still he has made both apply to either again, by saying, "one another," and showing that without peace it is not easy to edify.”
“Let us not judge one another in matters of this kind. Abstinence is edification; food, on the other hand, even if it does not ruin anybody, edifies no one.”
“He said "of peace" to the imperfect one, because that one did not have peace, and "for mutual edification" he said to the perfect one, so that he would not unsettle his brother by scandalizing him. However, by saying "mutual," he directed his word about this to both the one and the other. Moreover, by mentioning peace first and then edification, he showed that without peace it is difficult to edify.”
“Then when he says, therefore, he infers the intended admonition. Inasmuch as the kingdom of God consists in justice, peace, and spiritual joy, therefore, in order to arrive at the kingdom of God, let us follow after the path of peace, i.e., strive to accomplish the things through which we conserve the peace of Christians: strive for peace and holiness (Heb 12:14). Let us keep the things that are of edification, one towards another, i.e., things by which we upbuild one another, i.e., by which we preserve what is good and are stimulated to become better: strive to excel in building up the Church (1 Cor 14:12). Which indeed will happen if we have lived in justice and spiritual joy.”
“Since disapproval leads to discord, Paul teaches us to be peaceful and to avoid arguments over eating or not eating. Instead, he encourages us to follow the way of upbuilding.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
