The way of peace is through the wisdom taught in the Book of Proverbs, and through unity in the faith.
Life and Works of Rufinus with Jerome's Apology Against Rufinus. — translated by ANF/NPNF editors
44. In the end of your letter you say: “I hope that you love peace.” To this I will answer in a few words: If you desire peace, lay down your arms. I can be at peace with one who shews kindness; I do not fear one who threatens me. Let us be at one in faith, and peace will follow immediately.
