It probably depends on how one reads the OP's question. If we ask whether all doctrines are equally correct or if it matters in the long run every last thing that we believe...the answer is no. But if the question really is asking if God "cares" about our stands on all the lesser issues that divide us into competing denominations--all of that which is beyond the basics of the Gospel (Christ is Lord, salvation is by faith and trust in Him, we ought to strive to live as he taught in the Sermon on the Mount and in accord with the Commandments, etc.) then it's yes.
He is "indifferent" towards all of that, although I think the word indifferent is too strong. He is not "indifferent" towards the distinction between right and wrong, but he is not going to judge us on how we do Communion, what we think heaven is like, who is running the congregation, what exactly a sacrament is and how many of them there are, and so on.
