If the absence of the term “Sacrament of Penance” in Scripture proves there is no Sacrament of Penance, then the absence of the term “Trinity” in Scripture proves there is no Trinity.
In other words, the absence of the term “Sacrament of Penance” in Scripture proves absolutely nothing.
So why did you bring it up?
It demonstrates there is no sacrament of penance, except as imported from pagan religion, well after the death of the Apostles.
Pagan much, Arthur?
