In what particular way does it affect the Church's own work?
The problem is, it always does affect the Church.
So wading into the cesspool need not be so bad if you stop when it reaches your chin, eh?
Are they suggesting that such a thing could/should be blessed by the Church?I think they're just saying that such unions should be legally recognized, and such legal recognition need not be resisted by the Church.
No. Just accepting the fact that if state does something it doesn't need to affect the Church.
While I too groan at yet another sex or sexuality thread there is room for caution. In Europe it is quite common for those who want to push the boundaries to then use European equality laws, if necessary going all the way to The European Court. History suggests simple acceptance today of an innocuous proposal may in time result in consequences beyond the original proposal or in contravention of assurances previously given.
It is perhaps worth contemplating what is driving these social changes, and I suggest this is a Marxist agenda intent on dismantling or replacing current belief systems, institutions and social values. Not that campaigning for these changes are Marxists but, perhaps, might be what Lenin cynically called 'useful fools'.
