mauvepink-it is true that jesus is not recorded as addressing the subject of homosexuality directly. however he clearly delineated the boundaries of marriage as being as a "man being joined to his wife".in addition to this he was a practising jew and we know what moses is recorded as writing on the subject.he said that he had not come to abolish the law but to fulfil it;admittedly not giving details ,but pauls teaching on the subject tends to confirm the continuation of the OT view of homosexual practise.
i am aware that some interpret scripture to faciltate same sex unions but i dont think that would be the historically understood position.

i would differ from some of your christian friends inasmuch as i do believe there are degrees of sin,though any sin separates us from God but for Christs atonement.
it is worth saying that though same sex is strongly spoken against in the bible,other sins also are;eg adultery/divorce and pride.

though not agreeing with your position ,i appreciate the gracious way that you express it.
