This a personally timely article for me.  Many in my family are Protestant and actively involved in their Churches of choice...one, being a Lutheran minister, and a few in Music Ministry in their Churches, etc.  Last Wed. my husband and I had to priviledge of celebrating the Reformation.  Our niece is a wonderful musician, playing organ for different Churches for a number of years.  She puts on an organ recital for her community at noon in the Methodist Church; and at night in the Catholic Church.  That day, her repertoire was taken wholly from music written by Martin Luther.  One piece for each of the various seasons in the Liturgical Year.  A couple I was familiar with, the rest I was not.  But the most wonderful thing, was to hear her Pastor, give a explanation of how truly devoted to the Catholic Church, he had been!  My family is very "ecumenical" in flavor, so I have experienced both sides of the "coin" so to speak, and to hear this gentler side was truly breath-taking!
