John the Apostle
John 13:35BSB·traditional attribution

By this everyone will know that you are My disciples, if you love one another.”

John Gill Reformed Baptist

The mark that sets apart Christ's disciples is not strange dress, harsh austerity, or even spiritual gifts, many false disciples possess those. It is love for one another, plain and visible. The very pagans saw it and said, 'See how they love one another.' Would that it were as plain now.

Matthew Henry Presbyterian

When Judas left, I could speak freely at last. Christ is glorified by purifying His church; corruptions within it disgrace Him. Now that the traitor was gone, the family was clean, and He could pour out His heart without restraint.

Commenting on John 13:31-35

Albert Barnes Presbyterian

Deep, genuine affection for each other is how you shall be known, not by peculiar dress, speech, or austerity like the Pharisees. The first Christians bore this badge visibly; the pagan world remarked on it. Yet in our time, most commands of Jesus are less observed than this one, the want of true love even among those who share the same faith.
