Redemptive Suffering
Redemptive suffering is the Roman Catholic belief that human suffering, when accepted and offered up in union with the Passion of Jesus, can remit the just punishment for one's sins or for the sins of another. Like an indulgence, redemptive suffering does not gain the individual forgiveness for their sin; forgiveness results from God’s grace, freely given through Christ, which cannot be earned. After one's sins are forgiven, the individual's suffering can reduce the penalty due for sin.

My understanding is that Catholic is correct. Among things I have read is that Roman Catholic is an imprecise variant sometimes used in reference to the Latin Rite, that it was coined by Henry VIII to raise nationalist feelings and that it is sometimes used to imply we are only one of several Catholic churches.
Actually, any comments on this or a blog post to clear this up would be helpful.
