So let's take a minute to look at what Jesus did say, then we'll go back to what He didn't say. First, what was His attitude toward the Old Testament? Clearly, Christ regarded the Law and the Prophets as the Word of God. Whenever ethical questions arose, Jesus always referred back to the Scriptues, saying, "What is written in your law? How do you read?" (Luke 10:26) Again, He told the masses, "The scribes and the Pharisees sit in Moses' seat: all therefore whatsoever they bid you, that observe and do...." (Matthew 23:1-2) Does this sound like He has a problem with the Mosaic Law?
So just what did Moses say? Leviticus 18:22 reads, Thou shalt not lie with mankind, as with womankind: it is abomination." The very next verse forbids bestiality. Pretty clear, black-and-white, no grey area; but in case anyone missed it, Moses reiterates in 20:13, "If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination; they shall surely be put to death, their blood shall be upon them."
The fact that Jesus said nothing directly about homosexuality doesn't help the gays' case. If you wanna talk about what Jesus didn't say, He didn't say, "well Moses was just an old insecure homophobe anyway, so don't listen to him. God's positiion on homosexuality is evolving." What Christ did say is, "Think not that I am come to destroy the law, or the prophets. I am not come to destroy, but to fulfill." Matthew 5:17. Now if Jesus had a problem with the scribes and Pharisees' interpretation or applcation of the Leviticus sexual morality laws, would not He have called them out on this? But He never challenged them on this issue.
OK, what about the NewTestament? What was Christ's view of the Apostles' writings? "And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet. Verily I say unto you, it shall be more tolerable for the land of Sodom and Gomorrha in the day of judgement, than for that city" Matthew 10:14-15 And in Luke 10:16, "He that heareth you heareth Me; and he that despises you despise Me; and he that despises Me despises Him that sent Me"
So the person who rejects the message of the Apostles rejects Jesus Christ, and the Father as well.
Well, what did the Apostles say about homosexuality? The Apostles to the Jews didn't need to say anything, as Moses had already given us God's word on the matter. Paul, the Apostle to the Gentiles, taught the church at Corinth, "Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolators, nor adulterers, nor effeminate, nor abusers of themselves with mankind, nor thieves, nor covetous, nor revilers, nor extortioners, shall inherit the kingdom of God." 1 Corinthians 6:9-10.
And what did Jesus Christ have to say about ol' Paul? Only, "Be not afraid, but speak, and hold not thy peace for I am with thee." Acts 18:9-10. What He didn't say? "My Apostles have issues....don't worry about their homophobic rules." No! He told His Apostles, "Whosesoever sins ye remit, they are remitted unto them, and whosesoever sins ye retain, they are retained." in John 20:23.
So, you wanna argue from what Jesus didn't say? He didn't say Moses was wrong, and He didn't say Paul was wrong. He stood up for both of these men. And I'm not going to hold my peace either, 'cause I know from experience: if push comes to shove, He'll stand up for me, too.
