The main propositions defended by Febronius were as follows. The constitution of the Church is not, by Christ's institution, monarchical, and the pope, though entitled to a certain primacy, is subordinate to the universal Church. Though as the "centre of unity" he may be regarded as the guardian and champion of the ecclesiastical law, and though he may propose laws, and send legates on the affairs of his primacy, his sovereignty (') over the Church is not one of jurisdiction, but of order and collaboration ('). The Roman (ultramontane) doctrine of papal infallibility is not accepted by the other Catholic Churches and, moreover, has no practical utility. The Church is based on the one episcopacy common to all bishops, the pope being only first among equals.
