Just a fact-question, if you or anybody else can answer it:
I always assumed that a religious marriage involved a vow of permanence ("til death do us part" or words to that effect) made in the presence of God. I only recently realized that not all religious groups have such a vow, and some do not have explicit, spoken marriage vows at all!
So my question is: does a conservative Jewish wedding involve explicit vows, promises, pledges or whatever? And if so, what ar they?
Absolutely. A Jewish marriage is a formal, written contract (called a ketubah), signed, with witnesses, on the wedding day. This webpage explains both the traditional ketubah text (used by the Orthodox) and the Conservative, which Dennis Prager would have promised. See the Lieberman Clause, which was added to the traditional tex in case of civil divorce.
