text: I understand that it is complicated, no "but's" about it.  But the reality is that there is no movement of powerful groups towards RC recognition of ssm.  Therefore, no liturgical forms are available, so certificates of Catholic marriage have or will not be issued, and there is currently no avenue available for a dialogue on the matter.  The LG students I know well, some of them seriously coupled, have no intention - or need - for a church wedding in any church that rejects them, or for a growing number of them, any church-related wedding at all.  What you hope for is wonderfully Christian, but not a possibility in the Catholic church, and will not be for many, many decades yet.  I well understand why those who do want a church wedding go elsewhere, and for their peace of mind, they should.
