Infallibility | April 20, 2004

The inability to err in teaching revealed truth, claimed by the Roman Catholic church in Vatican councils I and II to belong to the church by the will of Christ (Luke 22,32 and John 16,13) and applicable in clearly specified circumstances to certain judgments of the pope speaking Ex Cathedra (from the chair, the symbol of the teaching authority) and the body of bishops in communion with one another and with him, either dispersed throughout the world or gathered in ecumenical council. The object of an infallible definition must be a doctrine of faith or morals proposed absolutely and definitely to be held by the whole church.
