Doesn't work.
Church leaders can and do err because they are human beings.
Here you appear to equate the Bishop of Rome with the Church. False. Likely you are mixing in a gross misunderstanding of the doctrine of infallibility.
I don't speak for The Holy Spirit.
I think that is an inconsistent position. I believe you claim to have the correct doctrine as guided by the Holy Spirit. There may be a distinction here, but little difference.
What is a church? Where two or more gather in Christ name that is a church and He is there also.
The Church; not A church. Here you confuse what the Church is - the Church established by Christ, given authority by Christ through His Apostles, etc. No one person is the Church, no two people are either.
the Holy Spirit helps us in our weakness.
Amen.
I made such claim where? Don't go there.
Your earthly church leaders have forgotten the early believers humble beginnings. Churches were in homes, in fields, wherever they could meet. The Church that Christ will return for aka The Bride of Christ has no name as it is the sum total of believers whom believe in Christ and accept salvation through Him. It is not Protestant nor Catholic in name.
The jealousy between Catholic and Protestants is much like the children fighting for the attention of a parent. Jesus addressed that issue with His Disciples as I posted earlier.
Mark ch 9 v 38John said to Him, "Teacher, we saw someone casting out demons in Your name, and we tried to prevent him because he was not following us." 39But Jesus said, "Do not hinder him, for there is no one who will perform a miracle in My name, and be able soon afterward to speak evil of Me.
