Im glad you asked this question The verses with the pork or swine: Notice how those verses are in the OLD Testement, Im pretty sure that is relating to the sacrifices, you would not usually use a pig for a sacrifice, usually it would be a ram or a goat. God put the animals on the earth for us, why would he put an animal on the earth if it had no purpose. It is perfectly ok to eat pork in the Christian belief. Alcohol: About the Alcohol related verse, God says do not get DRUNK with alcohol. Jesus himself drank wine. You see, if you are responsibly drinking, like a glass of wine, it is perfectly normal and not a sin at all. But, if you drink like 6 glasses of wine, to the point where you have no control over yourself than it is a sin. To drink alcohol is not a sin but to get drunk is. Its kinda like how the Bible says not to be a glutton, Proverbs 23:21 - For the drunkard and the glutton shall come to poverty: and drowsiness shall clothe a man with rags. A glutton is when you eat way too much food, some things are good, but too much of some things are a sin. I hope this clears things up for you.
