My parish is part of a neighbourhood ecumenical consortium of congregations and every year during the Octave of Christian Unity we have a pulpit exchange. I am not sure who represented our parish or where - Mother celebrated Mass and Father sat in choir - but we hosted a Basilian Father from a nearby parish. I was crucifer and sat with him on the sedilia. I was most gratified when he bowed to the Sacrament during the elevations.
