There has been some debate about authority, spiritual and temporal, and whether a good Christian should submit to it at all times, acknowledging authority as justified simply by virtue of it being there in the first place. I have a few thoughts about this but they come from someone who is not a member of any official branch of religion and consequently does not acknowledge anything in this world as having full spiritual authority so you may wish to reject them on those grounds.
What I would say is that this is a fallen world. You cannot assume that just because someone or something holds power that is in line with God's will, certainly not now when God is either denied outright or effectively denied because his commandments are disregarded even though he may be given nominal allegiance.
Obedience to external authority is not a virtue unless that authority is worthy and even then it is not a virtue as such though it may be right. Humility is a virtue and rebelliousness is a vice but obedience in itself is neither good nor bad. Besides, the whole point of obedience in a spiritual sense is so that we may reach a stage where we have learnt to think for ourselves. It's like the stabilisers on a bicycle before you can ride. This is not to say that disobedience is a virtue for it clearly is not except in particular circumstances when it may be right. But obedience is for children. Necessary if the children are to grow as they should and be guided into the proper ways of being and behaviour but stifling and infantilising if persisted in or insisted on for too long.
Jesus told us that the devil was the prince or ruler of this world. I don't imagine he was telling us to obey this prince while we were in the world. At the very least, he was surely saying that power in this world cannot be assumed to be given by God, and looking at history how can we doubt that?
Actually, I do believe in obedience but obedience to the voice of God within ourselves. You may ask, how can you know it's the voice of God? I reply you can't be certain but if it is and you obey it you will be given greater discernment whereas if you mistake your own self-will for the voice of God your mind will darken. By their fruits you will know them.
I had teachers whom I regard as spiritual authorities. They never asked for or expected obedience. They expected me to pay attention to what they said and if I had not they would have ceased to talk to me but they never asked me to think or do anything that did not make complete sense to me. I listened to them and I tried to apply their teachings because I respected them not because they were the authorities. They were authorities but that authority was rooted in truth as proper authority must be. If it is not (and can anyone really tell me that any authority is today?) then it is not spiritually legitimate and not only need it not be obeyed. It should not be obeyed because there is a higher authority.
We all need to obey the laws of the land except in extreme circumstances. But the greatest obedience is to God. He is ultimately the only authority and the only person we should obey. Yes, God delegates authority but in this present time the situation is that we are all being called to form a personal relationship with our Maker. How can we do that effectively if we listen to other voices?
