Option 4

Welcome family and friends to the marriage ceremony between _groomfullname_ and  _bridefullname_. _groomname_ and _bridename_ are thrilled that you could all be here with them to witness their marriage and celebrate with them their life commitment to each other, on this their special day.
Real love in marriage is something beyond the warmth and glow, the excitement and romance of being in love.  It is caring as much for the welfare and happiness of your partner, as for your own.

We are here today, not only to witness their commitment to each other as they become Husband and Wife, but also to wish them every happiness in their life together from here on in.
