(1) After faith nothing is required of us but love; as St. Paul says to the Romans, Cap. 13:8, "Owe no man anything, but to love one another: for he that loveth another hath fulfilled the law. What words St. Paul speaks to the believers who are now righteous and just through faith in Christ.
(2) This is a new commandment, which the heart desires, and not a hypocrisy; seek not only the good, but also souls and lives; so that we may present not only the good, but also the life.
*) Cf. Erl. A. 64, 258 and 15, 494. ed.
We must stretch ourselves for our brethren in vain, according to the example of Christ, who for nothing hath chosen us, and hath made us friends, and died for us. This one law of love kills and strikes down all our things.
Now you have heard much of the love of which this gospel speaks, and much has been written about it, so there is no need to make a special sermon about it; let him who needs it not be put off by the trouble and gather it together himself, so that one does not write a thing ten times and fill the world with books.
