Actually, Jesus said that some of the Hebrew scriptures, the Old Testament, were from the patriarchs and not from God.
John 7:22 "Yet, because Moses gave you circumcision (though actually it did not come from Moses, but from the patriarchs), you circumcise a boy on the Sabbath." Leviticus was one of these books. It goes against what Jesus taught and the covenant that God made with Moses.
Matthew 15:10-11
10 "Jesus called the crowd to him and said, “Listen and understand. 11 What goes into someone’s mouth does not defile them, but what comes out of their mouth, that is what defiles them."
Genesis 9:3 "Everything that lives and moves about will be food for you. Just as I gave you the green plants, I now give you everything."
Leviticus 11 is nothing but food prohibitions. It goes against God.
Sodom and Gomorrah was not about being gay. It was about having unloving hearts. The men of the town did not love. They just wanted to have sex with anyone with no love involved. Lot offered his virgin daughters to the men. He would not have done so if they were only interested in men.
Jesus spoke of circumcision of the heart, to have a loving heart and that to love God, you need to follow Jesus.
John 14:23-24
23 Jesus replied, "Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them. 24 Anyone who does not love me will not obey my teaching. These words you hear are not my own; they belong to the Father who sent me."
Jesus said to love God and your neighbor as yourself. He said that "All the Law and the Prophets hang on these two commandments." Matthew 22:34-40
He said that everyone is your neighbor. Luke 10:25-37 The Parable of the Good Samaritan.
Jesus also said over and over not to judge others.
You do not follow Jesus. Therefore, my dear sir, you are not a Christian because a Christian is a follower of Jesus. Know that God knows your heart and it is all about the heart.
Luke 16:14-15
14 The Pharisees, who loved money, heard all this and were sneering at Jesus. 15 He said to them, "You are the ones who justify yourselves in the eyes of others, but God knows your hearts. What people value highly is detestable in God’s sight."
1 John 4:8 Whoever does not love does not know God because God is love.
You have been deceived by the wolves in sheep's clothing.
Romans 16:18 For such people are not serving our Lord Christ, but their own appetites. By smooth talk and flattery they deceive the minds of naive people.
Do you not know that Jesus is returning soon? You should realize that you will face this.
Matthew 7:22-23
22 "Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ 23 Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’"
I fear for you. Please repent and come to Jesus before it is too late.
