23 The Holy Doctor's ready inclination for peace was shown especially when he mitigated his earlier severity and devoted his energies to bringing about reunion with the Bishops of the Province of Antioch. Referring to their ambassador he writes: He was probably expecting great difficulty in persuading us that it was needful to unite the Churches in peace and harmony, to deprive the heterodox of the excuse for mockery, and to repel the forces of diabolical malice. He found us, on the contrary, so much disposed to this course that he met with no difficulty whatever. For we are mindful of our Savior's words: 'My peace I give to you, my peace I leave unto you.'
