Wayne Grudem and John Piper some time back discussed baptism and ecclesiology. Piper longed to have a church membership that consisted of paedo-baptist and credo-baptists.
I use to hold to Pipers view. I had great admiration for he Free Presbyterian Church Worldwide. They hold this view. But as of the last few years my convictions have sharpened a bit. I hold a view that a local congregation is not the whole body of Christ. Unity in both places is very important but our Unity and Union are two different issues in my opinion.
Union seems to have more of a connection to something more than unity. When a union is entered into an attachment is achieved whereby others are put together as one. . Unity has to do with two walking side by side. We all have Union with Christ as a body but as a body has parts we are to walk in unity as members.
In our separate confessional standards we have a Union with each other in our individual Churches. 1689ers and WCFers so to speak have unions in their confessions. It is conviciton and confession that binds them. At this point there are a few issues that one goup must call the other out. One is congregationalism and the other is baptism. I do know of Presbyterians and Baptists who accuse the other of sin if one does not line up with the convictions of the other. The Baptist is accused of the sin of anabaptism by some Presby's along with the sin of not applying the seal of the covenant upon their children. These are not light issues as Piper does not address them. Some Baptist's accuse Presby's of poor hermeneutics in their understanding of Covenant Theology and sinning by not following Christ's command that disciples must be baptized as repentant converts of Christ. Disciples can not be infants or church members because one must first exhibit cognizant confessional capabilities. Therefore the Presby is knowingly admitting an unregenerate unforgiven Church membership that is not acknowledged in Jeremiah 31 or the New Covenant.
There are major differences that do not promote a Union but would in fact be a place where division would be caused by doctrinal differences. At the same time I do believe we can walk in Unity. For we have much more in Common with the beliefs we hold in common. For instance the Person and Work of Christ, the Five Sola's, most of our views on Covenant Theology. These are things we can walk in Unity concerning our faith and Practice. And our Union is truly with the Son of God.
I have been a PCA member. I joined with a promise not to cause any fuss over the issue of Baptism. And I didn't. I could never hold a position of authority in that Church because of my beliefs and my non adherance to the WCF. So another question for me to Piper would be.... Why in tarnations would you limit someone like R. C. Sproul, Pipa, Ryken, or any other good Presby in a Baptist Church membership or would you limit them? Would they be able to live out their convictons in good conscience in a 1689 confessional Church, or in your Reformed Baptist Church? If you are truly a Covenantal Baptist you couldn't. But if they dwelt amongst themselves they would not be limited in such a way. I would not let them perform their gifts of Elder in a Baptist Church or we would be in a compromised position to hold to our doctrine in my opinion. But at the same time I do hold them as Elders in the Church of Christ in their distinct Presbyterian Union. And I dearly respect them as Elders. And I would expect to hear the Word of God proclaimed by them in a goodly way.
The differences are to great in my estimation for such a mixed union.
