The problem is, that with everyone having the Masoretic Hebrew and Koine Greek Texts, the only way the RCC has to achieve product differentiation is to assert that their uninspired Catechism supersedes the truth and authority of the verbally and plenarily inspired, infallible, inerrant, preserved Holy Scriptures, and hence has
better truth.
Hmmm.
A dead soul, depending on their works to be worthy of God’s blessing and thus they believe Salvation, will latch onto any deception to continue supporting its pride. Catholiciism is based in feeding that fealty to sacraments pride at every turn and with each institutional dogma.
