So, at your service on Sunday morning (the actual service, not a Bible study or Sunday school or something else), there is a reading from one of the four Gospels EACH WEEK?
Do you have some way you can verify this? I know that Lutherans and Anglicans read from the Gospels each week, but I have NEVER heard of any other Protestants doing this. I looked at several OPC churches that were linked on the OPC website (a number of these churches hadn't updated their websites in years) and there was no indication that ANY of them read from the Gospels each week.
You know what? I got to thinking about this and I realized that it might make you uncomfortable providing verification due to privacy concerns and I respect that.
So, how about you provide me with a link to a SINGLE OPC church that is still in operation that shows where they have a Gospel reading EACH week at their Sunday service (remember, we are talking about an actual service, not a Bible study).
Here’s a link to OPC churches to help you out:
