So this is what I have so far. It is a work in progress. We are having a secular wedding.
It is with joy that we
Bride
and
Groom
Invite you to celebrate our wedding
Saturday the 17th of January
Two thousand fifteen
At five o’clock in the evening
Venue name
Venue address
City, Province
Dinner
and dancing to follow
Question: is "invite you to celebrate our wedding" okay? I chose this wording because we are not having a super formal wedding and "request the pleasure of your presence" seems so formal and stiff to me. Also, I want to make sure that this line implies properly that they are invited to a wedding ceremony. I am wondering if the wording "celebrate our wedding" gives off the impression that it is a reception/party and not actually the wedding ceremony itself.
