Sunday morning, Advent IV.
Sunday evening, Eve of the Nativity.
Monday, Christmas.
The only significant transfer taking place at my congregation is that we will move the location of the organist to the piano and use DSIV from LSB. I told my organist if she was worried about fatigue (she is a Lutheran school teacher close to retirement) that she could take Sunday morning off and I'd lead liturgy and hymns on the guitar. Our board of deacons discussed the option of not having services on Sunday morning, but we were in consensus that to go against the local church's good and pious habit was detrimental to the encouragement of faith and individual conscience.
