There was a theologian I read and respected. He was an expert on pastoral theology and first millennial church history.
He was having and crisis of faith many years ago and turned to a man he greatly respected, a Rabbi, and asked, perhaps I should be an adherent to the Jewish faith. His friend told him, perhaps you should try actually practicing your faith in its true depth before you start thinking of changing — see if that works.
His point was that (small “o” orthodoxy) is actually what is needed. Look at the tenants of your faith, your church, and practice those. Forget what others might be working on and “come and see” the Christ that has spoken to you over your lifetime.
If my faith wishes to invite all Christian believers to the rail, that is what I should try to adhere to in my orthodoxy. If my faith only wants members in full communion with my denomination, that is what I should be comfortable with in my worship. If my faith wants to only have members in full communion and of my particular church participate, that is something that an orthodox approach can accept as well.
Perhaps, in the practice of active Christian dedication I will be called to another denomination. If so, I am there to be worshipful and not to try and change them. I will be orthodox in my adherence.
