You have your own list of criteria... others come up with their own list of criteria.
Real spirituality doesn't involve joining a group. It's a one on one relationship with God. It is not following a group. Sooner or later someone in the group sets an agenda or egos become involved and the whole thing is corrupted. One ends up following man, not God.
"Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world. " James 1:27
And as others here have pointed out, Jesus said "wherever 2 or 3 are gathered together in my name, there I am in their midst." Doesn't sound like starting a new religion to me... Why settle for the substitute, when you can have the real thing? Jesus also said "I am the way and the truth and the life. No one comes to the Father except through me." John 14:6 The Truth is not an organization or a "true religion" It is Christ. All you have to do is ask Him.
