On Sacramentalism

Okay, so, admittedly, I have little knowledge on this topic (as I was lately so kindly reminded by a now-dear friend). It seems to me that the Catholic understanding of the sacramental life differs from the Calvinist understanding in that the former sees grace as typically mediated through the physical world, which for the latter that would mean a restriction on the sovereignty of God that cannot be tolerated. God acting through the physical world, then, implies a restriction on His power.


Perhaps this is connected to the distinction between will and being as the foundation for ethics: so Calvinists would root ethics in God's will and allow that that will might act arbitrarily. Calvinists might maintain that seeing ethics as derived from God's being places intolerable limits on God.
