This is not up for discussion. I’m not sure why even begin this thread. The Church has spoken on the matter. We have no right to question it.
If someone wants a clarification of the canon, there is an important detail. The law only applies to secular priests. If a man is a cleric and ALSO a religious, the rules and statutes of his community are the common law to which Canon Law often refers to.
To the best of my knowledge, no religious congregation and no religious order allows its members to hold public office, whether the person is a cleric or not. This would make perfect sense, because it would create a conflict of interests. A member of an order or a congregation owes obedience to his superior and to the statutes of his religious community. More than 50% of the time the statutes of religious orders and religious congregations are in conflict with civil law, because the rules written by the great founders of religious orders were divinely inspired and secular legislation is not divinely inspired. The statutes of religious congregations are not divinely inspired, but they are protected by the ordinary magisterium. Finally, members of religious orders and religious congregations have what is called conditional allegience to their homeland. The allegience is allowed only when it is not in conflict with the rule of the order or when it is not in conflict with a nation where we may have brothers or sisters. The allegience is disallowed when the civil law is in conflict with your religious superior’s position or the local bishop’s position. Your allegience must alwasy be to the higher authority. The hierarchy from top to bottom is the pope, the religious superior, the bishop and the state.
If you belong to an international order or international congregation, you cannot vote for a war against a nation where you’re brothers or sisters are going to be killed. Your first allegience is to them. It’s like attacking the nation where your parents live knowing that they may be killed. Who wants to be put into that position?
