Every one of you should form a choir, so that, in harmony of sound through harmony of hearts, and in unity taking the note from God, you may sing with one voice through Jesus Christ to the Father. If you do this, he will listen to you and see from your good works that you are members of his Son. It is then an advantage to you to live in perfect unity, so that at all times you may share in God. (Saint Ignatius of Antioch, +ca. 110)
