What is masonry religion?

are you talking about Masons like at the Masonic temple Masons?

I was in a Masonic youth organization, I had male family members who were Masons and female family members who were members of the women's auxiliary organization. The meetings are Christian-centric and all members believe in The Bible and Jesus. The members were of all different religious backgrounds, our meetings were in no way a replacement for Church but the group did promote fellowship and philanthropy, even as young teens we raised thousands of dollars for charities in our one little chapter and learned much about parliamentary procedure and public speaking. I kind of always assumed it was like the Elks or any other private clubs...

if you're talking about brick laying and stone cutting... I would assume its as much of a "religion" as any very skilled trade...
