Can a couple get married in a church if one is from the Church of Christ and the other is from the Seventh-day Adventist Church?
== == If the church is only a setting for the wedding, almost
anyone may be married in a church, generally speaking. Regarding
the person who officiates, I don't know the rules in the Church of
Christ, but an Adventist pastor would not be willing to perform a
marriage between an Adventist and someone of another faith: in the
Bible, it says to not be "unequally yoked," which for Adventists
means that you shouldn't marry someone who has different
beliefs.
A Seventh-day Adventist pastor has to be ordained in order to be
able to perform marriages. The position of the church is to marry a
non-Adventist couple or an Adventist couple. Marring a
non-Adventist with an Adventist is what the rule of the church does
not allow. But there is the other option, civil marriage in
court.
