What if one denomination is teaching that one is a helper or advocate other than the Holy Spirit?
What if one denomination is teaching someone tells Jesus what to do or who to save?
Should we be in agreement with that?
I think that all of us help others know Jesus by our words and actions. The Holy Spirit guides us, but we have a role that Jesus assigned us.
I also think that we can pray for Jesus and His Father to help others.
We also need to practice magnanimity in how we deal with fellow Christians, NOT to condemn them or raise hate toward them, which I seen in occasional Catholic and Protestants threads here on FR.
