“The Church of Christ, zealous and cautious guardian of the dogmas deposited with it, never changes any phase of them. It does not diminish them or add to them; it neither trims what seems necessary, nor grafts things superfluous; it neither gives up its own nor usurps what does not belong to it. But it devotes all its diligence to one aim: to treat tradition faithfully and wisely; to nurse and polish what from old times may have remained unshaped and unfinished; to consolidate and to strengthen what already was clear · and plain; and to guard what already was confirmed and defined”.
(St Vincent of Lerins, Early Church Father in Gaul)
