Fr. Tobias Haller BSG responds in a post to the argument made by some who oppose same-sex marriages (or unions of any kind) when they ask a question such as, “Why shouldnâ€™t three or more people be allowed to marry if they love each other?”
A polyamorous or polygamous grouping of people may claim to (and perhaps actually) share a loving relationship among themselves.

A multiply partnered relationship cannot be â€œmutualâ€ but must be â€œdistributive.â€
