I write the fifth Gospel, I teach the Synthesis Religion, which was the primeval religion of humanity, the doctrine of Janus or the doctrine of the Jinns. This is the religion of wisdom of the ancient sacerdotal colleges, of the Gymnosophists or solitary Jinns from Central Asia, of the Iohanes, Samoans, Egyptian ascetics, ancient Pythagoreans, medieval Rosicrucians, Templars, primeval Masons, and other more or less known esoteric brotherhoods, whose list would occupy a dozen pages.

This is the Secret Doctrine of the Knights of the Holy Grail. This is the Living Stone of Jacob, the Lapiz-Electrix (Magnes),
dialectically explained.

Without the fifth Gospel, the four former Gospels remain veiled. Therefore, I write the fifth in order to tear the veil of Isis.

It is urgent to unveil in order to teach. It is necessary to preach the Gospel of the Kingdom in all the nations of the world. To preach without unveiling is equivalent to not teaching. Therefore, we need to explain the four Gospels with the fifth one.

The Gospel of the Kingdom has never been preached, because it has never been explained. The four Gospels are in code. This is why no one could ever essentially explain them. Therefore, with the fifth Gospel, the light shines in the darkness. - Samael Aun Weor

The Gnostic Church instills tolerance as a principal virtue, leaving beliefs within the mind of believers.
