A self-uniting marriage is a kind of marriage where the couple getting married does not need a priest or someone else to marry them. They can marry each other without any outside help. It is also known as a "quaker" wedding because some quakers believe in these kinds of marriages.
When two people want to get married, they usually go to a priest or a court clerk and ask them to marry them. But in a self-uniting marriage, the couple stands up in front of their friends and family and says their vows to each other. Then they sign a marriage certificate, which makes them legally married.
This kind of marriage is legal in some states in the United States, like Pennsylvania, Colorado, and Wisconsin. In other states, it is not allowed, and couples must have a priest or a licensed officiant to get married.
Sometimes, couples choose self-uniting marriages because they want to avoid religious or traditional ceremonies, and they want a more personalized and intimate ceremony. For others, it may be a necessity because they cannot afford a priest or they live in a remote area.
In summary, a self-uniting marriage is a ceremony where a couple can legally marry each other without the help of a priest or someone else.
