Amongst Catholic Liberals, many go to Mass, even make novenas, and yet when they come into contact with the world, they lead the lives of practical Liberals. They make it a rule "to live up to the times" as they call it. The Church they believe to be somewhat out-of-date, an old fogy, that she is held back by a certain set of reactionaries, ultramontanes; but they have hopes that she will in the course of time catch up with the modern spirit of progress, of which they are the van. The barnacles of medievalism still encumber the Barque of Peter, but time, they believe, will remedy this. The straw of medieval philosophy and theology they hope before long to thrash out by the introduction of the modern spirit into her schools.
Then will a new theology be developed, more in conformity with the needs of the times, more in harmony with the modern spirit, which makes such large demands upon our "intellectual liberty" so they believe (or imagine they believe) that all is well. Is their responsibility before God therefore lessened? Assuredly not. They sin directly in the light of faith. They are less excusable than those Liberals who have never been within the pale of the Church. In short they sin with their eyes open.
