By the time John wrote Revelation 85% of the churches had gone seriously off track yet Catholics would rely on even later writings of non apostles. Makes no sense.
Cite your source. A reputable source.
Really? Off track . . . like so off track that most of the known world would be converted. Please list the “non-apostles” you are referring too - they must have really misheard the Apostles you speak of - clearly, someone in their home in 2015 reading a translated Bible is of superior sourcing.
