"The Catechism teaches that 'In order to preserve the Church in the purity of the faith … Christ who is the Truth willed to confer on her a share in his own infallibility.' Yet the Church also teaches that the gift of infallibility is limited. When is the Pope teaching infallibly? What authority does a Council of the Church have in defining the doctrines of the Church? What role does a Synod play in teaching the faithful what they should believe?"
