1 John 5:3

But there is another unholy kiss, full of poison, counterfeiting sanctity. Do you not know that spiders, merely by touching the mouth, afflict men with pain? And often kisses inject the poison of licentiousness. It is then very manifest to us, that a kiss is not love. For the love meant is the love of God. “And this is the love of God,” says John, “that we keep His commandments;” not that we stroke each other on the mouth. “And His commandments are not grievous.” But salutations of beloved ones in the ways, full as they are of foolish boldness, are characteristic of those who wish to be conspicuous to those without, and have not the least particle of grace. …

“With the heart man believeth unto righteousness, and with the mouth confession is made unto salvation. Wherefore the Scripture saith, Whosoever believeth on Him shall not be ashamed; that is, the word of faith which we preach: for if thou confess the word with thy mouth that Jesus is Lord, and believe in thy heart that God hath raised Him from the dead, thou shalt be saved.” There is clearly described the perfect righteousness, fulfilled both in practice and contemplation. Wherefore we are “to bless those who persecute us. …

But “the precepts of the law are very good,” if we use them lawfully. Indeed, by the very fact (of which we have the firmest conviction) “that the just and good God could not possibly have enjoined impossibilities,” we are admonished both what to do in easy paths and what to ask for when they are difficult. Now all things are easy for love to effect, to which (and which alone) “Christ’s burden is light,”, or rather, it is itself alone the burden which is light. Accordingly it is said, “And His commandments are not grievous;” so that whoever finds them grievous must regard the inspired statement about their “not being grievous” as having been capable of only this meaning, that there may be a state of heart to which they are not burdensome, and he must pray for that disposition which he at present wants, so as to be able to fulfil all that is commanded him. …

He afterwards adduces those passages which represent God as recommending His own commandments as not grievous: let us now attend to their testimony. “Because,” says he, “God’s commandments are not only not impossible, but they are not even grievous. In Deuteronomy: ‘The Lord thy God will again turn and rejoice over thee for good, as He rejoiced over thy fathers, if ye shall hearken to the voice of the Lord your God, to keep His commandments, and His ordinances, and His judgments, written in the book of this law; if thou turn to the Lord thy God with all thine heart, and with all thy soul. …

The Apostle Peter, likewise, says, “And, above all things, have fervent love among yourselves: for love shall cover the multitude of sins.” The Apostle James also says, “If ye fulfil the royal law, according to the Scripture, Thou shalt love thy neighbour as thyself, ye do well.” So also the Apostle John says, “He that loveth his brother abideth in the right;” again, in another passage, “Whosoever doeth not righteousness is not of God, neither he that loveth not his brother; for this is the message which we have heard from the beginning, that we should love one another.” Then he says again, “This is His commandment, that we should believe on the name of His Son Jesus Christ, and love one another.” Once more: “And this commandment have we from Him that he who loveth God love his brother also.” Then shortly afterwards he adds, “By this we know that we love the children of God, when we love …
