>>“While we believe that marriage is only between a man and a woman, we are not opposed to gay and lesbian as many claim; we believe in strict morality before marriage, regardless of sexual orientation.”<<
That is pretty much the Catholic position. You can have the attraction you just aren’t supposed to act on it.
But notice the verbiage.... “BEFORE MARRIAGE”. After marriage - anything goes?
WE all are born with sin nature. That is why the Apostle Paul referenced putting his old flesh to death daily... We are to resist the temptation to sin.
But that’s not the point here - is acting on sinful lusts only bad BEFORE marriage?
