This column represents the thoughts and opinions of The Rev. Carl Roth. This is not the opinion of the Elgin Courier.We usually use the word “flock” as a noun, to refer to a group of birds or sheep, but the saying “birds of a feather flock together” reminds us that “flock” can be a verb. “To flock” means “to gather or move in a flock” The Third Sunday of Easter each year is Good Shepherd Sunday. In the liturgy, readings, and hymns, the Lord as our Shepherd is the theme of the day. Christians are sheep of the Lord’s flock,
