Jesus was a pious man who achieved union with God, as the Oracle of Hecate related to the Platonic Philosopher Porphyry. This means Jesus is a purified soul who dwells amongst the gods. We believe the same for other great spiritual teachers like Hermes Trismegistus, Buddha, and Sankara. However, Jesus is not a primary figure of devotion in Romanism.
We don’t see Christianity as an illegitimate path. It has worked for many people for centuries. It also acted as a container for ancient wisdom and practices, meaning there is some overlap between Catholicism and Romanism. However, we differ in our understanding of God, the purpose of religious interpretation of sacred scripture, and much more.
Importantly, we do not accept that Jesus is God or the only salvation of man. Many other holy men and divine incarnations are outside of the Christian tradition. We also don’t accept the Old and New Testaments as infallible revelations regarding Jesus’ life and message.
