"If Christ has constituted one Holy Society (which He has done); if His Apostles have set it in order (which they did), and have expressly bidden us (as they have in Scripture) not to undo what they have begun; and if (in matter of fact) their work so set in order and so blessed is among us to this day (as it is), and we partakers of it, it were a traitor's act in us to abandon it, an unthankful slight on those who have preserved it for so many ages, a cruel disregard of those who are to come after us, nay of those now alive who are external to it and might otherwise be brought into it. We must transmit as we have received. We did not make the Church, we may not unmake it."
