Tractatus duo

Therefore, he will say and promise the same things that David said to Abiathar: original: "Qui quæret animam tuam, idem ille quæret & meam." "He who seeks your life will also seek mine" 1 Samuel 22:23. They will have common guests, acquaintances, friends, and (as is commonly said) enemies. Everything, in short, is common among friends, as the proverb says.

For Christian friendship aims at and looks toward promoting the glory of God, not at fostering and nurturing the errors of men.
