In modern times, Christianity has a problem with people who choose not to follow the people who are the appointed leaders. They believe that when the Church differs with them, the personal preference is to be heeded, not the Church. Such an attitude is understandable when we deal with Non-Catholics who do not believe that the Catholic Church is the Church established by Christ, or non-Christians and non-religious people denying Christianity altogether. The point of Christianity is that it professes to have revelation from God, and that people who have been entrusted with the authority of applying that revelation have their teaching backed by this revelation. So a person who does not believe Christianity possesses any such revelation, it stands to reason that they won’t follow the teachings of that Church.
However, when it comes to Christianity, which professes to believe in the God of the Old Testament and believes Jesus Christ is the Son of God, this faith necessarily presupposes that God has given us realization—through the Law, the Prophets and finally through His Son. When the Christian falls afoul of the commandments in some way, the fact is he or she is behaving in a way which God has revealed to us to be counter to the way He wants us to live. Furthermore, when God has revealed that authority has been given to certain human beings to bind and to loose (Matthew 16:19 and Matthew 18:18) for the purpose of bring the message of salvation and teaching His commandments so that people may live as He commands (Matthew 28:19-20 and Revelation 22:11), then obedience to that human authority is a part of being faithful to that revelation of God.
