Dear Arthur,
I already addressed your argument about forgiving sin. I also note Christ never says this passed to anyone outside the disciples.
Nor is there such a thing as the sacrament of penance in Scripture.
In regards to the Trinity, the word is not found in Scripture. The descriptive term was adopted to express the truth that Scripture does teach: that the Father, the Son, and the Spirit *all* have the attributes of deity. They are also separate Persons from each other. They are also One God.
All taught in Scripture.
The theological term “Trinity” expresses this truth in a succinct way.
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?
