Christian, remember your dignity, and now that you share in God’s own nature, do not return by sin to your former base condition. Bear in mind who is your head and of whose body you are a member. Do not forget that you have been rescued from the power of darkness and brought into the light of God’s kingdom.
Through the sacrament of baptism you have become a temple of the Holy Spirit. Do not drive away so great a guest by evil conduct and become again a slave to the devil, for your liberty was bought by the blood of Christ.
Take this example:
Jesus speaks about the worlds of both Noah and Sodom. He had them linked in His mind in this conversation.
Luke 17:26“And just as it happened in the days of Noah, so it will be also in the days of the Son of Man:27they were eating, they were drinking, they were marrying, they were being given in marriage, until the day that Noah entered the ark, and the flood came and destroyed them all.28“It was the same as happened in the days of Lot: they were eating, they were drinking, they were buying, they were selling, they were planting, they were building;29but on the day that Lot went out from Sodom it rained fire and brimstone from heaven and destroyed them all.30“It will be just the same on the day that the Son of Man is revealed.
What was the problem in the days before the flood? Somehow, I believe, it ties into the sin of Noah's son, Ham. It says that Ham "saw" and then Noah cursed Ham for what Ham "had done UNTO HIM".
Genesis 9:22And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without. 23And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness. 24And Noah awoke from his wine, and knew what his younger son had done unto him.25And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren
In Sodom the angels came to seek the righteous and ended up having to destroy the town. Before that, however, they had an encounter with the men of the city who wished to force sex upon them. That it was about sex is proved by Lot's offer of his daughters who hadn't yet had relations with men.
Gen 19:4Before they lay down, the men of the city, the men of Sodom, surrounded the house, both young and old, all the people from every quarter;5and they called to Lot and said to him, “Where are the men who came to you tonight? Bring them out to us that we may have relations with them.”6But Lot went out to them at the doorway, and shut the door behind him,7and said, “Please, my brothers, do not act wickedly.8“Now behold, I have two daughters who have not had relations with man; please let me bring them out to you, and do to them whatever you like; only do nothing to these men, inasmuch as they have come under the shelter of my roof.”9But they said, “Stand aside.” Furthermore, they said, “This one came in as an alien, and already he is acting like a judge; now we will treat you worse than them.” So they pressed hard against Lot and came near to break the door.10But the men reached out their hands and brought Lot into the house with them, and shut the door.11They struck the men who were at the doorway of the house with blindness, both small and great, so that they wearied themselves trying to find the doorway.
God destroyed both of those culures, one an entire world, and one a "city of the plain" culture.
Returning to Jesus' accusation of "marrying and giving in marriage". What is wrong with marrying? Generally, nothing is wrong with it. Jesus attended at wedding at Cana of Galilee and the Apostle Paul speaks highly of marriage. And, the marriage of man and woman parallels the union between Christ and His church.
However, Ham "did unto" his father Noah while his father was naked. That culture "married and gave in marriage" in an evil form that saddened God that He had even created mankind.
God destroyed the pre-flood world for "marrying and giving in marriage."
The Pope says that the future of mankind is at stake over gay marriage.
I would think so.
2 Thessalonians: 1Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. 3Let no man deceive you by any means: for that day shall not come, except there come a falling away first,
