Actually, I would have never come to the idea to see a hierarchy (like the CC has it now) in the verse above.
Yes, he writes that there are different offices in the Church (which is the community of believers; - and you will naturally disagree here!

), all these ministries are given by the Holy Ghost, as I have written two posts ago.
Aren’t also the (trinitarian) Churches, all of them, in agreement that Jesus is our savior and that he has died for us on the cross?
Is it a disagreement that you believe in honoring Mary, and I don’t?
What unites us is the believe in Christ! - So I would say, “No, there are no disagreements and schisms in the Christian Church”.
I am not speaking of the non-trinitarian Churches here, because they are cults and thus not Christians in my eyes.
