But the oath of conformity was not the chief oath made in the ordination process, as I also explained in that post. Ever since 1550, every Anglican/Episcopal ordinand on both sides of the Atlantic has vowed “to minister the Doctrine and Sacraments, and the Discipline of CHRIST, as the LORD hath commanded, and as this Church … hath received the same, according to the commandments of GOD”, or words to the same effect. (The current version has it this way: “Will you be loyal to the doctrine, discipline, and worship of Christ as this Church has received them?”)
Now, then, let us return to Canon Harris’ question. As he himself appears to recognize, Mark Lawrence eventually was forced, by the course of events leading toward same-sex marriage in ECUSA, to choose between “the doctrine, discipline, and worship of this Church” and “the doctrine, discipline, and worship of Christ as this Church has received it” (my bold emphasis).
