The york right which is an appendant body of masonry is Christian and requires a mason to be Christian.
Well, no. The York Rite is not Christian. Just one of its bodies claims to be - the Knights Templar Commandery which comes only after completing Blue Lodge (first three degrees) and after completing the Royal Arch Chapter degrees in York Rite which are not Christian. In York Rite, each degree is not given in weekend marathons of multiple degrees as in Scottish Rite. The Knights Templar Commandery is but one appendant body to Blue Lodge Freemasonry and the only one claiming to be Christian.
In any event, before one becomes a Knight Templar in Freemasonry, one has to complete all the degrees in their Holy Royal Arch chapter which includes the Mason who is exalted into the Holy Royal Arch having to learn and be lectured on the secret Grand Omnific Name for God -
Jahbulon. A Royal Arch Mason is taught that this is God’s real name and that God’s real name was hidden from him in the first three Masonic degrees (in the first three degrees one is given a substitute name and taught the word has been lost). Actually, some Masonic authorities say Blue Lodge is simply the outer portico for the Lesser Masonic Mysteries, and the Greater Mysteries come in the sanctorum of the Higher York and Scottish Rite degrees.
In the Royal Arch ceremony the candidate is told he cannot pronounce this secret name Jahbulon ever on his own, on pain of decapitation. As far as I know, most Royal Arch masons keep to this promise religiously. It is only pronounced when three Royal Arch masons gather and pronounce each syllable individually while they smack their hands, ie. Jah - Bul - On at the Royal Arch altar. So if one claims religion is not allowed in the Lodge, how does one then countenance
Mystical Lectures on God’s secret name. Of course this is religious.
The Royal Arch Mason is told the Freemason’s name for God is an amalgam of three deities or that each syllable in God’s name represents how the three original master masons, Solomon, Hiram, Hiram Abiff would have called God.
So before one can become a Masonic Knight Templar, one has to complete Holy Royal Arch where one is taught that God’s Omnific Name is Jahbulon, not Jesus Christ.
And Jahbulon, on many readings, is a combination of the Hebrew “Jah” with Baal/Bul, the pagan deity Elijah fought in the Old Testament, and “On” - the place where ancient Egyptians worshiped the Sun God Ra and later Osiris. Although we think of Baal as being a name for a pagan deity or the devil himself, in the 19th century the authors of the Royal Arch degrees attempted to combine him with Jahweh and Osiris, hence the name Jahbulon. In Macoy’s Masonic Encyclopedia, written around the time the Holy Royal Arch Ceremony was framed, Baal gets a positive definition. If you think this is Christian, well that’s hogwash.
So yes, in the Knights Templar body, the Mason is told this body is Christian, but before he reaches it he goes through Royal Arch and at the Royal Arch altar is taught a Secret Grand Omnific Name for God which has absolutely nothing to do with Jesus Christ. How many fraternities lecture their candidates The Secret Name for God lost to time, and give this lecture at a Royal Arch altar?
If you start giving lectures and ceremonies at altars where you learn the Name of God which is not to be revealed to the profane, you are a religion. And this is York Rite.
