Certainly you won't find this in my church, and I suspect that most of my non-Catholics friends here are the same. "Opinion" or preachign by the preacher are a part of the worship service, but not its totality. People go to sing songs of praise, to hear the Word read and to offer their prayers and concerns to the Lord.
Even if "opinion" is offered, it is not the main reason to attend a worship service. Worship, by praise and song is.

Show me a man appointed by GOD with a gift of knowledge like Paul.
Guess what, there aren't any.
You know that the above is true ?
Has God called you to such a knowledge or are you merely assuming ?
