But is that true?: John 5: 46: For if you believed Moses, you would believe me; for he wrote of me. 47 But if you do not believe his writings, how will you believe my words? 

Jesus spoke of the Torah, penned by Moses: Genesis, Exodus Leviticus, Numbers and Deuteronomy. 

Jesus said that what Moses wrote was true. Look at the part of the Torah penned by Moses: 

Leviticus 20:13 ‘If a man has sexual relations with a man as one does with a woman, both of them have done what is detestable. They are to be put to death; their blood will be on their own heads. 

Now, in the New Testament; 

John, Chapter 8: 8 1 but Jesus went to the Mount of Olives. 2 At dawn he appeared again in the temple courts, where all the people gathered around him, and he sat down to teach them. 3 The teachers of the law and the Pharisees brought in a woman caught in adultery. They made her stand before the group 4 and said to Jesus, “Teacher, this woman was caught in the act of adultery. 5 In the Law Moses commanded us to stone such women. Now what do you say?” 6 They were using this question as a trap, in order to have a basis for accusing him. But Jesus bent down and started to write on the ground with his finger. 7 When they kept on questioning him, he straightened up and said to them, “Let any one of you who is without sin be the first to throw a stone at her.” 8 Again he stooped down and wrote on the ground. 9 At this, those who heard began to go away one at a time, the older ones first, until only Jesus was left, with the woman still standing there. 10 Jesus straightened up and asked her, “Woman, where are they? Has no one condemned you?” 11 “No one, sir,” she said. “Then neither do I condemn you,” Jesus declared. “Go now and leave your life of sin.” 

Jesus didn’t make adultery OK, He just forbade hypocrites from punishing that sin with death by stoning. 

Adultery is still a sin, and God is still holy enough to punish it. So is homosexuality, as evidenced in the New Testament: 

I Corinthians 6:9-11 

9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God. 

1 timothy 1:8-11 8 

We know that the law is good if one uses it properly. 9 We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers, 10 for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurers—and for whatever else is contrary to the sound doctrine 11 that conforms to the gospel concerning the glory of the blessed God, which he entrusted to me. 

So, the concept of Tacit Acceptance is legitimate. Jesus did not speak openly (that we know of) about homosexuality, but by not countermanding Jewish scripture, we press Jesus’ Tacit Acceptance of Old Testament teaching on homosexuality, because we see those practices forbidden to the New Testament as well. 

Mark 3 

Another time Jesus went into the synagogue, and a man with a shriveled hand was there. 2 Some of them were looking for a reason to accuse Jesus, so they watched him closely to see if he would heal him on the Sabbath. 3 Jesus said to the man with the shriveled hand, “Stand up in front of everyone.” 4 Then Jesus asked them, “Which is lawful on the Sabbath: to do good or to do evil, to save life or to kill?” But they remained silent. 5 He looked around at them in anger and, deeply distressed at their stubborn hearts, said to the man, “Stretch out your hand.” He stretched it out, and his hand was completely restored. 6 Then the Pharisees went out and began to plot with the Herodians how they might kill Jesus. 

This scripture shows that Jesus confronted religious error, but left the permissible alone. If it ain't broke...
