Well, spoiler alert, I won’t really discuss what a cornerstone is like because I don’t know. I could do an in depth, i.e. three minute, internet search and pretend I know but I don’t think that would address any questions anyone might have anyway.
Our New Testament text this week talks about Jesus as the cornerstone, “So then you are no longer strangers and aliens, but you are citizens with the saints and also members of the household of God, built upon the foundation of the apostles and prophets, with Christ Jesus himself as the cornerstone.” (Eph 2:19-20 NRSV) I used this notion of cornerstone and foundation to answer the sermon title’s question, namely, “Foundation of what?”
In the end what I came to is that Jesus is the cornerstone of the foundation of a group that has no “in and out” binaries. In this part of Ephesians, Paul is talking about how at one time there was an unbridgeable barrier between Jews and Gentiles but Jesus destroyed that barrier. From there we can see that the church is for absolutely everyone. There are no excluded groups because entrance into a relationship with God depends on God reaching out to all people — the days of needing to be born into a particular family, clan or race are over.
Knox Presbyterian Foundation of what?
St. Mark’s Presbyterian Foundation of what?
This is another Sunday where there may be differences between the two messages. If anyone can see any differences and wants to comment on them, I’d love to hear about what you heard.
