“Since the Cross accounts for nothing in such a theology”
Actually Catholics believe Christ’s death on the cross and Resurrection mean everything. God is not encumbered in any way. However, we sinners are limited in out ability.
The worst thing we could do is to fritter away the great sacrifice of Jesus by throwing up our arms and wishing,,,”hey, that’s it, I’ve done my part by accepting this truth”. The Bible calls Christians to do things, attempt to emulate Christ as much as we can. We fall miserably short, but Scripture tells us to attempt to be like Him.
What did Christ do for you? What benefit was there in the cross for you?
