Over at the USCCB blog, Father John Crossin, executive director of the USCCB Secretariat on ecumenical and interreligious affairs, notes seven markers on the road to Christian unity. It is stunning to think how far we have come in what is, in Church terms, such a relatively short period of time! Indeed, we saw visual evidence of this just yesterday as Cardinal Donald Wuerl, in choir cassock, prayed one of the readings at the interfaith prayer service for the inauguration. There was a time, not too long ago, when RCs were not allowed to participate in such services!
