Can you explain what you mean by the term "manifested"?
In canon law, "manifested" means something that is widespread public knowledge not requiring significant effort to discern, something that is known or could be easily known by the majority of people.
I.e. a Pope who would leave the Catholic Church to accept nomination as the next Presiding Bishop of the ECUSA would be a manifest heretic and schismatic. John Kerry openly living with another woman not his wife without benefit of annulment of Church marriage is manifestly living in grave sin. Archbishop Lefebvre taking to the public airwaves to denounce the New Mass and Vatican II as abominations and publicly ordaining Bishops and Priests without jurisdiction is manifestly placing himself in a schismatic position vis-a-vis the Pope and heirarchy.
OTOH, Archbishop Ngo-Dinh Thuc secretly consecrating men to the Episcopate and ordaining Priests without publicity, witnesses, or formal records is engaging in acts that are not manifest but are rather secretive.
