Fallible means error, then I choose not to believe it.
No, fallible does not mean error. It simply means it does not have a 'certainty of faith'. Any priest, bishop or cardinal is fallible (every saint was fallible!)- that just means they COULD make a mistake. But they also could not. This is why our Faith is not based on MEN; it is based on DOCTRINE. It is based on a culmination of teachings over 2,000 years, including all infallible statements, and consistent doctrinal teachings. This is summed up in the catechism, which a 3rd grader can understand. OUR FAITH IS NOT COMPLICATED. Ergo, when V2 comes along and teaches something different from the Baltimore catechism, and do so NON-SOLEMNLY, then you reject it.
It only becomes complicated when we laymen try to understand it from a technical sense or when any catholic tries to question God's providence and ask 'how could this happen?' or 'Why?'.
Both infallible and fallible teaching proposed by the Magisterium should be generally accepted.
No. The pope is not an oracle. The bishops/cardinals, whether inside or outside a council, are not error-free. Our Faith is based on Christ and HIS teachings, not the teachings of the current men in rome.
What good is the Magisterium if we cannot trust it, if we have to inspect every sentence proposed to us looking for falsehood? The Catholic Church is known for its clarity and the ability to teach and reach the hearts and intellects to people from all walks of life, both the learned and the unlearned.
The situation in which we find ourselves is very unique to Church history. We have 2,000 years of consistent teachings, with multiple orthodox catechisms, with many learned Saints and Doctors to listen to.
God did not leave us orphans in the Faith, when He allowed the modernists to inflitrate His Church. He even provided us with 3 saintly popes right in a row (Pius IX, Leo XIII and Pius X) all of whom fought these same modernists and
St Pius X WARNED US sternly that they would come back! We knew this day would come and we have consistent teachings to compare V2 against.
The ordinary magisterium (i.e. the hierarchy) has never been thought to have ANY charism of infallibility, which is why when popes spoke of the magisterium in times past, they were speaking of the univeral magisterium, which is the CONSISTENT teachings over the years. It is only in our last 100 years that modernists have muddied the waters and started talking about the current magisterium as possessing some level of 'doctrinal authority', which is an error. No single hierarchy has any authority over doctrine because doctrine is Truth, which existed before the earth was even made, since it is part of God's nature. This is why the infallible magisterium is called 'universal' to denote that it never changes.
