Recently, one of my fellow chanters wanted to chant "O Pure Virgin" during the communion of the faithful at Liturgy. As I was protos for the day, I nixed this because it is simply not a communion hymn. NOw, I know some parishes do chant this hymn during the communion of the faithful, but that's hardly justification for my church to do likewise. But it does raise the question as to when this hymn could be sung. I know it's a "para-liturgical" hymn and really has no suitable place in a liturgy. I know it's a favorite among many Orthodox, but that, too does not justify its use. So, where have other parishes used it? Or is it just a spiritual song that people can sing outside of the church?
