1 Corinthians 13:3

Clement of Alexandria The Instructor Book II

And do you imagine that I am thinking of a supper that is to be done away with? "For if," it is said, "I bestow all my goods, and have not love, I am nothing."[11]

Clement of Alexandria Stromata Book VII

But it is not from the same cause, or with the same object; not were they to give their whole body. "For they have not love," according to the apostle.[90]

Tertullian Against Praxeas

was the first to import into Rome from Asia this kind of heretical pravity, a man in other respects of restless disposition, and above all inflated with the pride of confessorship simply and solely because he had to bear for a short time the annoyance of a prison; on which occasion, even "if he had given his body to be burned, it would have profiled him nothing," not having the love of God,[7]

Cyprian Epistle LXXII

s Christ before men and is baptized in his own blood? And yet even this baptism does not benefit a heretic, although he has confessed Christ, and been put to death outside the Church, unless the patrons and advocates of heretics declare that the heretics who are slain in a false confession of Christ are martyrs, and assign to them the glory and the crown of martyrdom contrary to the testimony of the apostle, who says that it will profit them nothing although they were burnt and slain.[31]

A Treatise on Re-Baptism by an Anonymous Writer

On which principle also, that heretic who, by confessing Christ's name, is put to death, can subsequently correct nothing, if he should have thought anything erroneously of God or of Christ, although by believing on another God or on another Christ he has deceived himself: he is not a confessor of Christ, but in the name only of Christ; since also the apostle goes on to say, "And if I shall give up my body so that I may be burnt up with fire, but have not love, I profit nothing."[39]
