I'm not sure which "secret oath" you're talking about, but if it's the infamous Knights of Columbus "secret oath" quoted in the Congressional Record around the year 1915, you should know:
- It was read into the Congressional Record for the purpose of denouncing it as a forgery, a context which Catholic-haters invariably forget to mention
- It's a forgery
- Because it's a forgery, it's banned on the FR Religion Forum
Real Christians don't willingly believe lies about other people. Even if you don't consider us to be Christians (you're wrong), Catholics are still "other people".
It is a reference to the banned "knights of columbus oath" fraud. I followed his link.
