@Ben Zartman - Can you give me the name of one person in your local congregation whom you know is a member of the New Covenant? The first name will suffice so as not to give away the identity. After you've provided the name, can you tell me the basis of your knowledge that this person is in the New Covenant?Ahhh, not so! One of the glories of the new covenant is that only the elect are in it--I'm glad someone sees the baptist position here, even if you disagree with it...baby steps. Peter alluded to the Abrahamic covenant because here was the real fulfillment of God's promise to Abraham: that his descendants would be as the sand of the sea. Not his physical descendants, though their great number was a type of the real thing, but spiritual descendants. The multitude in Acts finally understood--the promises to Abraham weren't about Palestinian real estate, or innumerable physical descendants, but about spiritual seed. It's kind of sad that presbyterians want to return to the physical aspect of Abraham's promise when it was something so different.
