This Sunday is Pentecost or "Whitsunday" as it is known in the English tradition and in the Book of Common Prayer. There are lots of proper readings for this week. The Communion Propers are Acts 2:1-11 and St. John 14:15-31. There are also proper Psalms and a proper First and Second Lesson for Morning and Evening Prayer. The BCP ties in diverse themes to show how Pentecost is an eschatological event where the Spirit makes God's dwelling place in man once again, but this time through the conversion of His people. Pentecost also brings in the nations, as the kingdom of the Messiah expands beyond Israel to the ends of the earth.
