Surely you jest. The Calvinists, need I remind you, are the ones who believe that whatever "mandate" believers have is pre-determined and that nothing that they can do or not do has any bearing whatsoever on acheiving God's purposes.
Catholics believe that God has put us here and given us the grace we need to make His Kingdom fully known. And we believe our actions matter.
You're totally incorrect.

No, I'm not "totally incorrect". Just because you have a misperception of Reformed theology and have been inculcated thoroughly in greek dualisms does not mean I am totally incorrect. It appears you have no understanding of how God's use of Covenants dictate the blessings and curses his people will receive. When His people are faithful God blesses them with all manner of blessings including the building of His kingdom. Just because you cannot in your own finite understanding resolve how God blesses people with salvation and requires responsibility to his elect does not negate the fact that we are creatures and He is the Creator. If we live in the here and now to glorify God in faithful obedience then God will build his kingdom. It is really that simple. I don't need to worry about whom may be elect because I know that God will use me to bring those who will come according to His own good will. My responsibility is to be obedient to His word and allow God to work through me as He pleases. All blessings come from God. Now that you have a better understanding I would hope that you would desist in your simplistic characterizations of biblical doctrine.
