Puritan Board Professor
This is easy to say on an internet forum friend. I don't disagree, but we also need to live in the real world and attack the bigger issues first. In both the PCA and the OPC, there are several issues of orthodoxy that need to be worked out that I believe take precedent. For the PCA, the sodomy issue. For the OPC, the issue of feminism and observing the sabbath (perhaps the PCA has this one too).
In both the OPC and PCA, Sessions of individual congregations determine how to serve the Supper. Sitting around the table is not contrary to the worship standards of either the OPC nor PCA. It is nothing that needs to be changed denominationally or before the Presbytery. It is something your local Session needs to reform. So again, determine what Christ requires for you, be not concerned with the whole of the OPC or PCA, what about your congregation? What does the Lord command? Now, if you come to the belief that God requires sitting around a table (same with wine), then go prayerfully, humbly, and submissively to your Session and ask them to study the issue for the health of the body. That's what I mean when I say, "Orthodoxy comes before orthopraxy".
