Let me first say this: As you can now see, we are not led by blind obedience as the jungle claimed. We have free will. Like everyone else, we can sin. We can disobey. As humans, we can fall. It is true that Archbishop Hon was sent by the Pope, and we are supposed to be obedient and respectful to him. Yet, this happen and God allowed it to happen. Our catechists never taught us blind obedience. They told us that it is good to obey God, the catechists, the priests, the Archbishop, the Pope, our parents, our teachers, our elders, etc. But they also taught us that we have free will.
Now, to answer your question: The Bible not only tells us to obey the Bishops, but it also tells the Bishops to care for their sheep. The Bible tells us that children are to obey their parents, but it also instructs the parents to care for their children. Shepherds, parents, and all those in authority always set the examples for us to follow. When they set good examples, we tend to follow those good examples. When they set bad examples, it is also human nature to follow those bad examples. In other words, when parents break their promises to their children, in time children will also learn to break their promises to others.
Disobedience can be a sin depending on the circumstances. The Catholic Church looks at the REASON or INTENT for the sin of disobedience. They also look at whether the person had full knowledge of the consequences of the sin and their consent in committing the sinful act. Therefore, disobedience can either be a venial or mortal sin depending on these factors. If a person disobeyed because he is being asked to do something immoral, that is NOT a sin. We are obligated to follow God's commandment above everything else; therefore, it would NOT be a sin if we are asked to steal, kill, etc. On the other hand, if he disobeyed a command that is not immoral but because he disagrees with it, that could be a venial sin. If he disobeyed a command for the purpose to slander, discredit, and destroy someone's name and reputation that would be a mortal sin.
The first person to show disobedience was Archbishop Hon (the very person whom the Pope sent). According to Father Mike in the Patti Arroyo talk show, he revealed that the FIRST thing that Archbishop Hon did was try to remove Archbishop Apuron. Archbishop Hon sent a letter asking Archbishop Apuron to resign. There was no response from him. So, Archbishop Hon encouraged the Presbyterial Council to vote for Apuron's removal. These were Archbishop Hon's first actions. This was disobedience to the Pope. As to whether it is a venial or mortal sin, I would prefer to let God be the judge of that.
After encouraging the Presbyterial Council to remove Apuron, he went to Rome to ask Pope Francis to have Apuron removed as Archbishop of Agana. And what happened while he was in Rome? Both Father Jeff and Father Mike disobeyed their superiors. This should come as no surprise. After all, it was Archbishop Hon who taught them disobedience. Disobedience often breeds disobedience. Father Jeff instructed Father Mike to read the letter and distribute the petitions. He disobeyed because he disagreed with Archbishop Hon's decision and felt that the alleged victims should be more important than the Church's assets. Was that a venial or mortal sin? Father Jeff, on the other hand, disobeyed Cardinal Filoni because his intent was to discredit the integrity of the RM seminary. Was that a venial or mortal sin?
Shortly after Archbishop Hon cleared Monsignor James' name, the Cemetery Board filed a complaint to GPD and the AG's office against Monsignor James. They accused him of misappropriation of funds and submitted evidence to show that. They did not obtain Archbishop Hon's permission. Was their disobedience a venial or mortal sin? What was the reason and intent for going to GPD and the AG's office? Did they feel that the truth should be told about both Monsignor James and Archbishop Hon?
In light of the sex abuse scandals and cover up in the past, many Catholics can be torn between loyalty to the Church and honesty. If Monsignor James is actually guilty of misappropriation of funds as the evidence appear to imply, should the Cemetery Board be honest about it or should they be loyal to an Archbishop who may be covering up a criminal activity? Either way, the Cemetery Board can also be guilty of sin by remaining silent.
No one ever said that life was easy. We each have to make our own decisions. But before making those decisions, we need to examine our conscience and discern whether we are doing it for the good of others, for correction, for ourselves, for the destruction of others, etc. In the end, God will be the judge because He knows the heart of each person.
