Romans 12:10

“Be kindly affectioned one to another with brotherly love, etc..] This is one branch of that love, before advised to, which should be unfeigned, and without guile and deceit. The objects of this grace are “brethren”, not in such sense as all the descendants of Adam are, or men of the same country be, or as such who are born of the same parents in a natural sense are; to each of whom love is due under their respective characters and relations: but such who are so in a spiritual sense, who are born of God, are of his household, belong to his family, are the brethren of Christ, and one another; and are either members of the same church, incorporated together in the same church state, or at least…”

“Be, &c.--better, "In brotherly love be affectionate one to another; in [giving, or showing] honor, outdoing each other." The word rendered "prefer" means rather "to go before," "take the lead," that is, "show an example." How opposite is this to the reigning morality of the heathen world! and though Christianity has so changed the spirit of society, that a certain beautiful disinterestedness and self-sacrifice shines in the character of not a few who are but partially, if at all under the transforming power of the Gospel, it is only those whom "the love of Christ constrains to live not unto themselves," who are capable of thoroughly acting in the spirit of this precept.”

“Be kindly affectioned - The word used here occurs no where else in the New Testament. It properly denotes tender affection, such as what subsists between parents and children; and it means that Christians should have similar feelings toward each other, as belonging to the same family, and as united in the same principles and interests. The Syriac renders this, “Love your brethren, and love one another;” compare 1 Peter 2:17. With brotherly love - Or in love to the brethren. The word denotes the affection which subsists between brethren. The duty is one which is often presented in the New Testament, and which our Saviour intended should be regarded as a badge of discipleship; see the note at…”

“In honour preferring one another - Which you will do, if you habitually consider what is good in others, and what is evil in yourselves. Romans 12:11”

“12:10 genuine affection: Literally brotherly love. Christians are to love each other with the mutual love and commitment that are found within a healthy family.”
