predestination beliefs

Reformed Protestants believe that God selected individuals at the time of the beginning of the world and predestined those individuals for salvation. Orthodox believe that God knew at the time of the beginning which individuals would choose to believe and on the basis of that foreknowledge predestined those individuals for salvation. Is there any theological school of thought which believes that what God predestined is that salvation would be given by grace through faith -- in other words, that God predestined a process, not a set of persons?
