Again, there are no vows. There is no “I do” that’s only in western Christianity due to the legal contract aspect of marriage in western theology that *does not exist in eastern theology* it’s considered worldly in eastern theology. In eastern Christianity the priest goes over whether or not the couple consents to being married *before* the wedding. Long before! It is a requirement in order to have a wedding in the first place. After receiving that consent the wedding can take place. Traditionally consent is received prior to the betrothal service which is separate from the wedding service even! But these days those services are often combined.
