Umm, no, the Scripture actually does not say that. One quote, taken out of context, says that and a text, out of context, is a pretext for a proof text. I'll be happy to teach this Bible lesson again if you need it. Simple version, Matthew 5 refers to frivolous oaths AND can be a reference to the higher standard Christians should try to achieve in the world, similar to hatred being equal to murder and lust being equal to adultery. The biggest blow to this false "no oaths" teaching? Christ took an oath in Mark 14.The scripture says so. Society has lulled believers into accepting broad general oaths that they can never truly keep nor finish as they do not understand that by swearing it on the Bible that they are going to do something without God's help. It is their vow & the swearing of it is to declare their sincerity not only to do it but to to finish it. The keeping of any oath is the work of man's hands for why God will judge it.
But why do it?
People complain about self serving politicians and breaking their promises from their campaigns to get elected in the performance of the office they hold, so why do it?
Same with the military. People have been court-martialed and even dishonorably discharged so what power does the military oath has? It cannot make the vower keep the vow. All the law does is expose the sin by that vow and thus adding double penalty before God for when the vows are broken.
Looking for assurance by the deed of the law to make a person good and to do good is vain and an offense to God.
Look at the witness vow in the judicial court system where they are to tell the truth, and nothing but the truth so help you God. But His words says He cannot help you tell the truth; you either do it or you do not. Then the court will instruct the witness to answer the question put to them in an yes or no answer or else be fined contempt of court, but not every question can be answered in a yes or no by the witness. Can God help that witness there? No. All they really need to do is instruct the witness the penalty for lying on the witness stand because as it is, people have lied on the witness stand regardless of making the oath to tell the whole truth.
Adding extra wedding vows of love from each potential spouse to God's covenant of marriage may very well be why there are so many divorces because love is not boastful and for the Christian, they are supposed to be relying on Jesus Christ all the time by His words that He will supply all the love they need along with other fruits of the Spirit in blessing their marriage in bring fruitful.
This is Hollywood & and the world's programming into seeing what looks like that everybody is doing it and so it must be okay, but it is not..
Even Alcoholics Anonymous & Narcotic Anonymous all have each addict choose a higher power and make a commitment to stay sober; the reward is given to them keeping that commitment; not to the higher power helping them no matter if the addict think that higher power which can be a tree, Britney Spears, or Jesus Christ. So while addicts roll their eyes to each addict's higher power, the credit for their sobriety is given to each addict keeping that commitment. Why? They did it. Not their higher power. And the Bible agrees, even though God knows if they really kept it or not and will be judged by it.
Do you look to yourself to fulfill the duty of your office by keeping that oath and failing the letter of it? Do you believe you will be found justified by the keeping of that oath in Heaven to God having sworn it on the Bible? Then ask Jesus to forgive you, set you free from that oath, and trust Him to help you fulfill the duty of your office in doing good while being good by His grace & by His help.
As it is, my question to you is, can Christians drop Mason from that Lodge and just make it a Christian Lodge, having no oaths in it but keeping the faith in Jesus Christ that He is in us & with us always as we trust Him to help us be good & to do good by His grace & by His help?
Or is there an higher authority reigning over all lodges that no lodge cannot do that?
Which really blows your entire point away since virtually everybody takes some form of oath in both the ancient and modern world.
As for your example of military members failing to keep their oaths, that falls flat on its face because it is a double standard. Many who claim to be Christian are not, but by their actions and words is Christ condemned and His words made false? God forbid.
Oh, for your last bit: No, there is no central body in regular Freemasonry that controls "world wide masonry" or any other such claptrap. The core of any authority are the Grand Lodges, which derive their authority from the local lodges (sound familiar?). The Grand Lodges, in accord with each other establish rules and relations between themselves. Grand Lodges who act wildly and outside the standards of regular Freemasonry are not recognized.
