The organization works to promote interdenominational marriages while encouraging each spouse to remain an active member in their respective branch.
The organization works to dispel negative sentiment about interchurch marriages and educate mixed church couples about the changing pastoral rules and advocates instructing the children from these marriages in both branches of the faith.
Failure to follow those rules may result in an annulment of the marriage by the Catholic Church.
It seeks to link all those families, groups, and associations so that together they may grow in Christian unity, by affirming at local, national and global levels the gifts of interchurch families and while realizing their potential as a catalyst for wider church unity.
The association also produced a bi-annual journal with changing rules and pastoral practices until 2004, but has since switched to an email newsletter.
