So you honestly believe that Indulgences came from Muslim jihad?
And references for that or just conjecture?
The Good Thief received an indulgence from the cross.
Protestants should follow his example, especially since he did the good work of defending Christ while he was on his own cross.
The thief on the cross received forgiveness. He didn’t have to do anything, nor do we.
Roman Catholics would do well to follow that example. Only faith in Christ…and only Christ will save you.
