Tertullian

Come now, you who deny the salvation of the flesh, and who, whenever there occurs the specific mention of body in a case of this sort, interpret it as meaning anything rather than the substance of the flesh, (tell me) how is it that the apostle has given certain distinct names to all (our faculties), and has comprised them all in one prayer for their safety, desiring that our "spirit and soul and body may be preserved blameless unto the coming of our Lord and Saviour (Jesus) Christ? " Now he has here pro-pounded the soul and the body as two several and distinct things.

But when is peace more to be concluded with brethren than when, at the time of some religious observance, our prayer ascends with more acceptability; that they may themselves participate in our observance, and thereby be mollified for transacting with their brother touching. their own peace? What prayer is complete if divorced from the "holy kiss? " Whom does peace impede when rendering service to his Lord? What kind of sacrifice is that from which men depart without peace? Whatever our prayer be, it will not be better than the observance of the precept by which we are bidden to conceal our fasts; for now, by abstinence from the kiss, we are known to be fasting.
