Using scripture is more than a legitimate source of research and often seen in Protestants posts when debating the issues....Further, catholic ‘literature’ has been proved in error in the past, even they “change” their own history time and again , so it would certainly seem unreliable Historically.
Additionally, what is often seen in catholic writings when they do use scripture, is that they tend to twist and bend scripture to align with their doctrines rather than let scripture determine what their doctrines should be. Which is an abuse of scripture.
The same was done in the Garden and when Jesus was in the wilderness....so it is no surprise that mis-use of scripture continues to this day to justify beliefs, dogma and various other things which Jesus never instituted nor required of his true believers saved by his Grace.
