There was] the temporary suspense of the function of Ecclesia Docens [teaching Church] as about 80 percent of the bishops fell into heresy.First of all, this statement refers to Bishops, not the clergy overall, nor does it include the Pope. Your statement refereed to the clergy overall, and is contradicted by your own quote which indicates the clergy stood firm. Second, it is well known that many of the Bishops only fell into this heresy under force, and recanted as soon as that threat was lifted. While that does not speak well of their character, it is hardly the same thing. Few contend that a confession of faith elicited under torture or threat of death is a true confession.
