My conclusion is that what has been wrong has been the conclusions drawn by people about situations proscribed in the Bible.
It’s not the Church that is arrogant. The Church itself isn’t subject to arrogance. But the people within it are - and there hasn’t been a single sinless one of them. Ever. From Saint Peter, with his thrice fold denial and his foolish tempestuousness onwards, every single person that has ever walked this earth has relied on human ability to draw conclusions. And for a long time people have abrogated their own responsibility to question conclusions that have been handed down, instead trusting that people before them had done all the work necessary and they only needed to believe what they were told without questioning.
Well, thankfully, we are no longer required to believe blindly. Since we were allowed to read the Bible for ourselves, we have all been allowed to be ‘doubting Thomases’ and see the evidence for ourselves.
The evidence is there: St Paul - in the Greek and in the translations - speaks of the sin of heterosexual men giving themselves over to homosexual activity and wilfully rejecting that which was natural for them.
No honest person can therefore escape the corollary that it would be equally sinful for a homosexual person to give themselves over to a heterosexual lifestyle by wilfully rejecting that which was natural to her or him.
We are what we are by the Grace of God from the moment of our conception. It is not for us to question our natural being.
Yes, the Church may well never allow homosexual unions to be sacramentalised - and that isn’t a problem if the sacrament is related to unions that are open to the creation of life because that new life is, itself, sacrosanct and a gift from God and deserves to be held within a sacramental status. But that doesn’t mean that men and women who find themselves to be homosexual should live lives of despairing loneliness without the companionship and mutual support of one another that married couples enjoy. That would be cruel and unusual and to deny people that love, that joy, that safety, that mutual support, spiritual complementarity and connection is and can only ever be sinful if you really and truly believe that Christ Himself commands us to love one another.
It cannot possibly be and is not loving to deny someone else the chance to love the person whom they are naturally created to love.
And if that means I’m not a Catholic, then so be it. If the Pope (who, thankfully, seems to be much more enlightened on these matters than many of his flock) wants my membership card back, then I’ll gladly give it up. But nobody well ever persuade me that forcing someone into a life without love is a good idea.
