“[John Calvin] believed that compromise and ambiguity could be legitimate on issues of secondary importance in the life of the church but not in the foundational theology of the church.” (John Calving: Pilgrim and Pastor by W. Robert Godfrey, p. 59)
On several occasions Calvin met with Lutheran and even Catholic leaders in an effort to see if some common ground could be found and an understanding reached.
I am a Calvinist. I was not raised in a Reformed theological tradition. I came to subscribe to Reformed theology through the study of Scripture. Nevertheless I find no difficulty in working with believers across the Christian spectrum. In a few weeks I’ll have the pleasure of preaching from Mark 10. In vv. 38-41 Jesus, it seems to me, rebukes the disciples and warns them against sectarian disputes. So what if they’re not one of us. If we agree on the foundational issues of Christian faith, then what matters the rest?
I am a Calvinist who can worship and work with Arminians just fine.
