Is the full inclusion of gay and lesbian people into the life of the church the most challenging task of all? How did we get to the point where a person's sexual orientation became the greatest barrier to their involvement in church life?
I am of the firm conviction that the vast majority of people with a homosexual orientation are naturally inclined that way. It's not a choice they make because they want their lives to be more difficult or something that can be simply cured by enough prayer - it's just how they are. If I'm correct about this (and I know there are many who disagree) then I don't see that anyone has the right to forbid gay and lesbian people from entering into lifelong, loving relationships with each other.
In every other area of life, gay and lesbian people have proven their capacity including in leadership roles. Our social service delivery is greatly enhanced by their contributions. We all lose by making our churches unfriendly and unaccepting places simply because someone has a different sexual orientation.
