Let not those who seem worthy of credit, but teach strange doctrines, fill thee with apprehension...
The Revd William May, an orthodox Lutheran pastor in Milwaukee, quotes St Ignatius

‘Nada te turbe’ as St Teresa of Ávila, commemorated this Sunday, wrote. Or as the Psalmist sang: Be still then, and know that I am God.

Something that Fr Amphilochios knew.

Give ye heed to the bishop, that God also may give heed to you.

Of course St Ignatius assumes a Catholic bishop, that is, one acting unequivocally in the name of the Catholic Church (not necessarily his own opinions), but point taken.
