There’s nothing esoteric about the Christian faith. There is no secret mystery into which you must become initiated in order to be admitted. It’s not like the Gnostic sects where one had to become an initiate for years before he became a full member. Jesus spoke to this issue plainly when He said,
I have spoken openly to the world. I always taught in synagogues, or in the temple court, where all the Jews assemble, and I didn’t teach anything secretly.
Christianity isn’t Masonry, or Mormonism, where you take vows “never to reveal and always to conceal” rituals that you are required to perform in a Lodge meeting or in a “temple” ceremony. It has always been completely aboveboard about its beliefs and practices.
Indeed, as Jesus said, He always spoke “openly.”
If an organization—or pseudo church—has anything worthwhile to offer, let it be open to examination. How can anyone vow to never reveal something before he knows what it is? That is one form of what the Bible calls a rash vow. It is sinful to rake a vow that one doesn’t know whether or not he ought to keep before he knows what it is he is vowing to keep secret. Suppose, after taking a vow, one were to realize that he must expose the error or sinfulness of what he learns—he’d then find himself in an intolerable position. On the one hand, he’d be obligated to expose it; on the other hand he would have vowed not to do so. That is an unacceptable dilemma, one into which one must never allow himself to be inveigled.
One more thought—if a group of any sort has something worthwhile becoming a part of, it has no right to conceal it from anyone; but like our Lord said, it is something that should be proclaimed “openly to the world.” If it’s worthwhile, spread it abroad; why would you selfishly cling to it as private truth? If it’s not something worthwhile, then don’t get into it in the first place.
On every score, then, no Christian should ever become involved in a secret society. A fundamental principle of our faith is to preach the message of salvation to all the world. We have nothing to hide.
