The church calendar day is Pentecost. In our congregation that is also the day we do confirmation. I think this sermon explains the deep connection these things should have rather well. It also serves as my poor gift for those that have suffered under my tutelage in the faith the last couple of years.
A long time ago Israel received the Law on this day. Still a long time ago the Spirit was poured out on this day. And Pentecost stands on the calendar as exactly what those confirmands stood for today – a chance to renew the covenant of law and spirit that has been given to us.
