Mormons, is your dad or husband the mouthpiece of God?

What happens when a wife receives a revelation that the LDS is complete and utter bunk, but the husband doesn't? Can the wife leave the church without her husband's approval?

OF COURSE SHE CAN. And not because her husband allows her nor the constraints of her religion. She can because she is a citizen of the United States, where church affiliation or attendance is not required by law. That's why.

There may be a humanly decided upon "mouthpiece" within mormonism, but there is no "mouthpiece" within Christianity. There is the abiding relationship between God and the individual believer, where gender, marital status or social cultural practices become completely immaterial to both parties.

Every man, woman, and child has the right to personal daily revelation with respect to their areas of responsibility. In that regards, we are all mouthpieces of God. The husband presides over the family, and within his area of responsibility in the family he is the mouthpiece of God The woman, like the man, has areas of responsibilities, and is likewise the mouthpiece of God within those areas of responsibility.

The Holy Ghost is a really high priority in Mormonism. Without it, we are without a rudder so to speak and are left to the ever changing winds of men's philosophies, mingled with scripture. In the LDS church, husbands and wives are taught to counsel together. God can speak to individuals and counsels. As a counsel comes together in unity, the spirit guides each member and revelation is produced as the spirit creates agreement.

As a kind of practical matter, there must be one who presides at a counsel. In the family, this is the husband and father. He guides the discussion and makes sure that all are heard. It would be abusive for a husband to stomp on the opinions of others in order to selfishly have his way.

"For where two or three are gathered together in my name, there am I in the midst of them". Matthew 18:20

You could say that anyone could be a mouthpiece for God if they speak in the right capacity. It just depends on who they are, what they are saying, etc.

My father does have the right to receive revelation from God regarding his family, just as I have the right to receive it for mine. My mother and my wife also have those rights, respectively.

Within Mormonism, the man presides over the family, and has "stewardship" over his family. Thus, he is entitled to receive revelations from God for his family. The woman must promise to obey her husband, as he obeys God.

no, but parents are defined as the authority over the family, while bishops are stewards over wards and stake presidents have authority over the areas of several wards. theologically the Prophet only is the mouthpiece of God and Jesus Christ, with the quorum of the twelve presiding over the church in leadership.

Does your father or husband tell you that he speaks for God for you and the kids because he is prophet, seer and revelator for the family???
