Fratelli Tutti: On Fraternity and Social Friendship
58 The Book of Job sees our origin in the one Creator as the basis of certain common rights: “Did not he who made me in the womb also make him? And did not the same one fashion us in the womb?” ( Job 31:15). Many centuries later, Saint Irenaeus would use the image of a melody to make the same point: “One who seeks the truth should not concentrate on the differences between one note and another, thinking as if each was created separately and apart from the others; instead, he should realize that one and the same person composed the entire melody”.
