we have thousand of denominations due to division. Leaders have their 'own' understanding and opinions after they read the bible. It's sad I think it's how the Lord want it to be done. If you read the church history all the way up to now, you'll see godly servants of the Lord broke from their origin church and start their own denomination, some turned out to be good and some became really bad, in short no perfect church. Well it's sad and hard to swallow to see so much division for someone who's new to the faith but it's the reality.
I personally believed God is in charge of this, until Jesus's 2nd coming it will stay what is it, what do you think?
(different groups or churches is challenging to a new believer, he might ask 'so which church/community should I go to?')
It is important for all churches regardless denomination or non-denominations, to hear what the Spirit have said to the churches throughout time in the Holy Scripture.
Therefore, individuals are called to live by the Holy Spirit. Many who are called the Lord Jesus Christ as their Lord, still walk according to the old nature, and they should repent in order that they avert the disgrace that they dread that is spoken in Psalm 7:12-16.
We are called to bear with those who are weak. We are also called to suffer for what is right, and that include to show grace to them, just as the Lord forgives us.
It is of importance that all of us be found in the surpassing greatness of knowing Christ, not having our righteousness of our own but righteousness that comes through faith in Christ, that is, righteousness from God and is by faith.
For from the first to last, the righteous live by faith.
Read Psalm 50, you will come to know when Lord Jesus Christ comes, this is what He speaks.
Nee believer, no need to feel challenged in anyway, to which church to go ! For we are the church including new believers! What we should seek is the Lord’s strength, the Lord’s presence, the Lord’s face continuously!
New believer, together with all who the Lord Jesus Christ their Lord and ours is seek the Lord wholeheartedly and shall find Him.
