Can anyone please help as soon as possible? Thanks in advance

The following statements are both held to be true by Catholics. How can a Catholic understand both of these seemingly contradictory statements be true? (you may answer this question using the blind man and the elephant analogy if you know it)

Statement one: The Church, guided by the Holy Spirit, will not make an error in matters concerning faith and morals.

Statement two: A human being must always obey the certain judgements of his or her conscience. If he or she were to act against it, he or she would condemn his or herself. This assumes that a person will seek to make his or her conscience informed. ​
