In reply to the ?
No, it is not representative of all. I'm probably considered liberal by mainline UPC churches but I'm still solid
Acts 2:38.
There are several oneness organizations represented on this forum as well as a few who accept the trinity.
This forum is on its 3rd or 4th name. The faithful posters have changed.
But at it's core it is still a method for oneness Pentecostals to converse.
Often with differing opinions
But, I have found the discussions to be learning experiences. We do not need to be in lock step in order to live for the Lord.
If you're new to a Pentecostal experience, the forum may not be a good fit.
The exchange of opinions is not always in agreement with most OP pastors.
For me sixty + years associated with the UPC; Baptized and filled with the HG in 1960.....3rd generation oneness.
The forum is entertaining and educational but can also be irreverent.
Just be aware, and be strong in your beliefs. And enjoy!
