The lectionary for Sunday is a doozie. You can find the collect and readings here. Our parish is using Track 2, so it's Jeremiah (not Sirach) and Psalm 84. The Gospel is a rich one: the Pharisee and the tax collector go up to pray. Marvelous fodder for contemplation and preaching ... if only I'm up to the task.
At the moment,this is pretty much how I'm feeling.
