SEV Biblia, Chapter 13:35
En esto conocerán todos que sois mis discípulos, si tuviereis amor los unos con los otros.
Clarke's Bible Commentary - John 13:35
Verse 35. By this shall all men know, &c.] From this time forward, this mutual and disinterested love shall become the essential and distinctive mark of all my disciples. When they love one another with pure hearts, fervently, even unto death, then shall it fully appear that they are disciples of that person who laid down his life for his sheep, and who became, by dying, a ransom for all. The disciples of different teachers were known by their habits, or some particular creed or rite, or point of austerity, which they had adopted; but the disciples of Christ were known by this love which they bore to each other. The primitive Christians were particularly known by this among the Gentiles. Tertullian, in his Apology, gives us their very words: Vide, inquiunt, ut se diligunt; et pro alterutro mori parati sunt. "See, said they, how they love one another, and are ready to lay down their lives for each other."
John Gill's Bible Commentary
Ver. 35. By this shall all men know , etc.] Not only by this you yourselves will know that ye have passed from death to life, that the true work of grace is begun upon your hearts; nor only by this will you know one another to be Christians; but by this all men, even the men of the world will know, that ye are my disciples, if ye have love one to another : and own and acknowledge it, as Tertullian says the very Heathens did in his time; who would say, when they saw the Christians pass along the streets, and meet and express their affection to each other, “see how they love one another”: would to God the same was as observable now. The distinguishing badge and character of a disciple of Christ, is not any outward garb, or any austerities of life, by which the disciples of John and of the Pharisees were known; nor were the ordinary nor extraordinary gifts of the Spirit, bestowed upon the disciples of Christ, what distinguished them as such; since those who were not truly his disciples, had these bestowed on them; but love to one another, brotherly love was the distinguishing character, and this is another reason or argument enforcing a regard unto it.
Matthew Henry Commentary
Verses 31-35 - Christ had been glorified in many miracles he wrought, yet he speaks of his being glorified now in his sufferings, as if that were more tha all his other glories in his humbled state. Satisfaction was thereb made for the wrong done to God by the sin of man. We cannot now follo our Lord to his heavenly happiness, but if we truly believe in him, we shall follow him hereafter; meanwhile we must wait his time, and do his work. Before Christ left the disciples, he would give them a ne commandment. They were to love each other for Christ's sake, an according to his example, seeking what might benefit others, an promoting the cause of the gospel, as one body, animated by one soul But this commandment still appears new to many professors. Men in general notice any of Christ's words rather than these. By this it appears, that if the followers of Christ do not show love one to another, they give cause to suspect their sincerity.
