This site basically makes the false assumption that Sola Scriptura (bible as sole rule of faith) is a true doctrine and that Catholic Tradition violates Scripture. Scripture, in fact, says Scripture is not the sole rule of faith.
He also proof-texts Scripture to support the doctrine of sola fide (slavation by faith alone) which didn’t exist until the 1500s. A complete reading of Scripture refutes these things. Jesus constantly says that we must obey the commandments and do the will of the Father. The book of James is primarily concerned with refuting faith alone.
The author of this site asks a bunch of questions about Scripture to support his view that we should all be able to just read the Bible and come to all truth. Sola Scriptura was invented in the 1500s and since then, sola scriptura churches have splintered into thousands of denominations all teaching different things. This shows that we can’t just read Scripture and come to the Truth. We need the Tradition that shows how we are to interpret Scripture as well as the Magesterium which preserves that Tradtion.
He also forgets the verse that says the Church is the pillar and foundation of truth, the verse that says people will twist Scripture to their own demise, and the section where the eunach is reading the Scripture and he needs someone to help him understand it
Finally, he makes broad sweeping statements about what people agreed with over history. He also leaves out other historical evidence which refutes his claims.
Basically, this site is a classic example of unsupported and unteneble historical claims, strawman arguments, false assumptions, and proof texting.
