I have been thinking about this question… my imprecise answer so far is:
The desire to know Christ, to want/appreciate a united but diverse Christian body, and to worship in at least one of the historical Christian denominations.
These things, and the admission that none of our religious beliefs are certain, but any and all of them may be wrong.
With many of us, it might involve also the willingness to revise our beliefs in the face of new evidence.
Brandon,
Years ago I had a friend whose father was a Baptist pastor. The friend was involved in activity to support a pregnancy center to help young women in crisis. The minister father councilled young women in his church when they found themselves in trouble, that it was ok to have an abortion. It was his opinion that before a woman was three monthds pregnant he could not see that the child in the womb was a person, a human life, so it was ok to kill it to make woman’s life easier.
Keep in mind that Baptists believe all their moral doctrine should come from the Bible. I asked him how he came to this position and he said he personally could not be sure that before three months there was a human life there. I asked if he was in a parking lot and saw some kids and got in his car, put it in reverse and looked in the rearview mirror and saw a flasho of something go behind the car, but was not sure what it was, would he hit the gas, or be safe just in case there was a child there. His personal position made no sense.
He asked me how we could know whether or not in a life and death situation what to do. I said we need to know truth about it. He anwered with the question Pilot asked Jesus, “What is truth”. I said the Church teaches truth. He said sarcastically that my Church (Catholic) teaches truth, says it does, or thinks it does. I said that is right.
This made him angry. He said no church has all true doctrines. They all have some errors and it is arrogant to think you know truth.
I asked him if some of his Baptist group’s doctrines were false. He said of course. I asked which ones are false. He became more frustrated at what he thought was a stupid question and said he could not know and if he did know he would stop believing them. I said if you do not know which of your dictrines are false, then it is impossible to know which are true.
But you set yourself up as a shepherd of souls. You tell people with questions and proiblems of a spiritual nature how they should deal with them, and tell girls to abort their babies if they are so inclined, and you say you do not know truth.
The truths about life are not discoverable by the power of our finite minds. Jesus said He is Truth. He taught men He called and sent them to the nations to teach. We learn truth from them by believing in faith, not figuring it out on our own, but once we know it it makes sense intellectually.
If you are a math student and I am not and there is a difficult calculus problem I can not figure out, but you do and tell me the answer, then I know the answer by belieiving you, by faith. It is reasonable that I believe you, because you have some credentials as an authority in the subject. It is reasonable I believe my doctor who tells me what health problem I have and how to treat it, because he studied medicine and is a recognized authority.
God trained and sent His apostles into the world to reveal His truth. The things, doctrines, they taught are still believed by some, but have been distorted and changed by others. Jesus promised to lead His Church into ALL truth, never to abandon us, to be with us until the end of time.
You will be able to discover truth, but you will not be able to reconcile the contradicting confusing doctrines of the denominations and nondenominations, and if there is a postdenominational Church, it will be a result of reunification to the Church Jesus founded and built on the rock.
