As far as I am concerned, most definitely. Anyone who is honest about it will tell you that the the parts of the ceremonies about which we don't speak pose no threat to anyone. In these ceremonies, we promise to keep God's commandments as spelled out in the scriptures (which are available for anyone to read if they desire to do so). We also learn things that we believe are necessary for our salvation. Despite what other may tell you there is nothing in the ceremonies about taking over the world on any of the other wild stories you might hear. That being the case, there is no reason why any honest person should feel it necessary to break the vows they made. Whether those who leaves the Church believes it or not, they did make those vows to God. Therefore, to break them is to break faith with God. If we were using the temple to hide illegal activity or push forward a plan for world domination, then someone might be justified in breaking the vows. However, we are not; so they are not. *********** Addendum: Let me draw a comparison to other organizations. When people go to work for various government organizations or industries, they may learn things that they are not permitted to discuss with other people. When these people leave those jobs, they are still required to keep these secrets. For example, when my father was in the Air Force, he learned things that were required for his job that he was told he was not permitted to discuss with people outside of the service. He left the Air Force over forty years ago. So, those secrets that he is keeping are probably long obsolete. However, he still won't discuss them because he does not know if they have been declassified. Personally, I would not even dream of asking him to discuss them. To do so would be to ask him to break a promise that he made. The same applies to the temple ceremonies. As I wrote above, there is nothing in the ceremonies that threatens anyone else. So there is no reason to break the oaths that they make. Therefore, those that do so are proving themselves to be oath-breakers and, therefore, untrustworthy.

Technically, there are no oaths taken to keep the temple ceremony secret. The only oaths to keep anything secret are for a tiny portion of the ceremony, not the ceremony as a whole. That being said, the oaths taken are not made conditional on someone's membership as a Mormon. In my opinion, leaving the Mormon church does not relinquish oaths that were made independent of one's membership in the church.

I can attest to what you are saying is true from my own work experience but we are talking about something much higher and more important the are jobs here. If I take an oath to what I thought was God and then later on found out that he wasn't the true God (whether Mormon or Christain) my oath would not be worth anything. It is only as good as the one you put your faith in. *************** I would suppose that according to an LDS member, a person choosing to leave the Church are still under the oaths they have taken. They believe that these oaths were taken to God. Logically thinking... a person leaving the Mormon Church no longer believes in the God of the Mormon Church and therefore can not be under an oath to this God. If these people talk about "secret" ceremonies, they shouldn't be considered dishonest. In fact, if they are speaking the truth, how can they be considered dishonest?

They are still under the covenants they made with God, usually leaving the Church or being excommunication shows breaking those covenants or not believing them anymore

Why should any people of faith have secret anythings?

The oaths are, in fact, still in force.

I would think that if it is an oath made to God, then it is a moral decision that only you can make.
