Seems OPC uses TE/RE as well for Minister & Ruling Elder. But to your other point they do see 3 different ordained offices for governing the church.

I think the language of the OPC (in addition to the real distinction in offices) is better. In the 3 office denominations, there is no confusion between the official duties due to similarity in names.
