In the Bible, Jesus promised to remain with the Church and preserve the Church in truth. What does this mean? The current teaching is that this refers to the infallibility of dogmatic propositions taught by the Magisterium.
However, there is a serious problem with regarding theological propositions as infallible. Human language is a limited medium of communication. There are always many possible ways of interpreting a propositions. Also, no single proposition can perfectly express an idea. Furthermore, can we really say that human propositions can express the revelation of God, who by his very definition, is beyond expression?
An alternative interpretation of the promises is that they refere to the indestructability of the Church in its pilgrim journey in Truth. Though the bishops and Pope may err at times, the Church continues to survive and renew itself in the Gospel message. What do you think of this?
