Ecumenical activities at Catholic parishes pretty much came to a screeching halt early in the papacy of JP II, and assumed a less vibrant character with the advent of the so called JP II-B XVI priests and bishops, and the restoration of the "extraordinary" (Tridentine) form of the Mass.  Under current Catholic clerical leadership at the parish and diocesan levels, we will have a much more challenging (difficult) situation when it comes to any kind of "progress."
