Our rabbi often holds reconsecration [ceremonies] as a regular part of our Friday night services for anniversaries in multiples of 25 years. After the Torah service, at a time when couples normally would be called up for wedding, anniversary (multiples of five years), or special birthday blessings, the couple is asked to come forward. Their children and/or family members and/or friends are asked to accompany them, and to hold a small portable chuppah. Rabbi does a short [ceremony] (5-10 minutes), modified from the old rabbi's manual of the CCAR, which includes renewing of vows, and wine. It is a very meaningful few minutes, not only for the couple, but for the entire congregation, many of whom know the couple and may be there by special invitation. No special marketing is done for this; members of our congregation are contacted regularly to offer them blessings and/or bimah honors for the special events mentioned above, and it is suggested at that time.
