Rollock explains that temporary faith is different from historical faith (and other sorts of non-soteric faith) and that it shares many elements with justifying faith. Rollock says:
The reason of the name is this; it is called Temporary, because it endures but for a time, because it hath no root.
It hath the same object with justifying faith, and which is properly so called, namely Jesus Christ with his benefits, offered in the word of the Gospel and in the Sacraments; wherein it differs from historical faith, which hath for the object thereof the universal truth. It hath the same subject with justifying faith; for it hath its meat both in the mind, and also in the will and heart.
