Responsible & fruitful dissent will by definition be loyal. Loyal to the Gospel, to our early Christian community, to the teachings of early Church Fathers & Mothers and its Doctors of all ages, to the Eucharistic tradition and the 
Mystical Body --- not to the romanized, absolute monarchy, whoever may be the Pope or occupy the Curia.

The deeper problem is that church polity needs radical reform, radical in the sense of recovering its authentic roots & properly (re)conceiving the papacy. I believe the Holy Spirit will effect this realization, whether via institutional reform, noninstitutional vehicles or both. And an ecumenical reconciliation of Roman, Anglican, Lutheran, Eastern Orthodox & more will be hastened by these very reforms!

Oremus.
