The easiest way to get what you want is to ask for it.
I’m sure there are people who will say to me that you don’t absolutely need your community’s support to thrive in marriage. But if you have it you’ll do better. We thrive in community.The best way to get your community’s support is to tell them during the wedding that you want their support. You ask this question instead of asking the “does anyone object” question. You can ask the question “will you support this couple in marriage?” People will say “We will.” That will be helpful. But far more helpful is asking the community to make a statement. Have your celebrant make a statement that they can repeat which promises their love and support.
Tip: People take these promises seriously. They will remember. They will offer their support when you need it. And just as importantly, they will celebrate with you when you succeed!
