An individual, gender does not matter, comes to your church during a mid-week day and says, "I was walking by your church last Sunday and heard your choir singing. The music was beautiful. I would like very much to join your choir." "Are you a Baptist," they are asked. "No, but I do have a good voice and can read music." "Are you a Christian?" they are asked. "I think so," they reply. "I grew up Catholic." Would this person be welcome in the choir of your church? If so, why? If not, why?
