It is apparent to YOU that same sex marriage is not valid. The law sees differently. Catholic teachings hold that civil divorce is invalid, yet do you deny that the state has the authority to issue divorces that are legally binding. Similarly, the state has the authority to say that same-sex civil marriages are legally binding.

You are arguing in favor of willful ignorance. It is firmly established, at least as far back as Aquinas, in Catholic moral theology that a person who is wilfully ignorant is as morally culpable as one with full knowledge. If Mr Tennes truly believes that only those the Catholic Church says may marry can get married in his venue, it is clearly his duty to ascertain if either (or both) members of a couple who wish to marry in his orchard are divorced and to drive away those who do are. He is endangering his soul and the souls of the couple by permitting them to marry in his orchard. Or are his (and your) indignation selective?
