One of the more recent challenges for Catholic parishes is how to welcome L.G.B.T. parishioners, as well as families with L.G.B.T. members. But that challenge is also where grace abounds because L.G.B.T. Catholics have felt excluded from the church for so long that any experience of welcome can be life-changing—a healing moment that can inspire them to go to Mass again, return them to the faith and even help them to believe in God again.
