Hi brother,
We are indeed living in difficult times and need the guidance of the Spirit and the Word more than ever before,while not ignoring the council of truly wise godly men.
What I have learnt is that we are called to believe in the Lord Jesus Christ and , when we do this, we are baptised into the "universal" spiritual body of Christ.
We are, therefore, a part of the "church" whether we want it or not.
Also remember, that any group claiming to be a christian church, are dealing with Christ's body, not their own little kingdom. Christ is Lord and no man or woman and we are all to serve one another in common reverence for Christ and are all called to submit ourselves to His word and the teachings as laid out so clearly by the apostles in the epistles.
If the teaching of the church or their leadership clearly opposes the above, well......?
The challenge comes with the physical expressions of the church, where imperfect human beings at different spiritual levels come together, to teach and be taught, to worship, and to serve one another
You must decide for yourself, by the guidance of the Holy Spirit, whether the fellowship you are in is one in which you can contribute and also, receive spiritual encouragement, and whether your conscience allows you to put up with the things you disagree with, for the sake of the gospel and of Christ and your own spiritual well being
Of course, certain deal breakers are things like; false teaching and blatant heresy, the denial of the core tenets of our faith etc.
In the end, I usually turn to one of my favorite life passages from Proverbs:' Trust in the Lord with all your heart, lean not to your own understanding. Acknowledge Him in all your ways and He will make your path straight'
In conclusion, commit this to God in prayer, ask for His wisdom and guidance and trust that He will guide you according to His will
I know how frustrating this can be so I pray the above prayer in agreement with you
God bless,
William
