One seeking to disparage Christianity said:

“Documented, ancient history has it where Christianity was legalized in Rome in 313 AD, which should tell those of you something!”

Is that true? A Roman Emperor named Constantine, desiring greater control over the masses in the Roman Empire, envisioned an opportunity to coalesce the people under the Edict of Milan (312-313AD); Constantine, wanting to make Christianity attractive to the masses, opted to merge Roman and Babylonian paganism with elements of Apocryphal doctrine sprinkled with Christian doctrine thereby forming the World’s 2nd-largest religious cult aptly named “Catholicism” – 2nd-only to Islam in its deception and death in Hell; this, no different than those who seek the Kingdom of God via the self-righteous religion of Judaism.

Catholicism has never been Christian but there does exist those who hate Christianity and choose to insult that which Christ initiated in His own blood by suggesting Catholicism is Christianity, Peter was a Pope. Your obfuscation only finds relevance with those who seek death in Hell through religious works and the rejection of Jesus Christ as Messiah.
