Philip Schaff on walking the theological tight-rope (perhaps insight into why we have so many controversies in the Church with both sides appealing to the “Reformed Tradition”):
“Calvin thus combined his high predestinarianism with a high view of the Church and the Sacraments. Augustine and Luther did the same to a still greater extent, with more prominence given to the sacramental idea. It is the prerogative of great minds to maintain apparently opposite truths and principles which hold each other in check; while with minds less strong and comprehensive, the one principle is apt to rule out the other. In the Catholic and Lutheran Churches the sacramental principle gradually overruled the doctrine of absolute predestination; in the more rigid Calvinistic school, the sacramental principle yielded to the doctrine of predestination. But the authoritative standards are committed to both,” (Creeds of Christendom, vol. I, 457).
