For it has seemed good to the Holy Spirit and to us to lay on you no greater burden than these requirements: that you abstain from what has been sacrificed to idols, and from blood, and from what has been strangled, and from sexual immorality. If you keep yourselves from these, you will do well. Farewell."
(Acts 15:28-29 ESV)
Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.
(1 Corinthians 6:9-10 ESV)
Those who say that Acts 15 (among other passages) means God's commands about what animals we should and shouldn't eat no longer apply need to explain the enormous contradiction between these two passages. Of course, the only way to explain this apparent contradiction scripturally is to conclude that the apostles did not throw out all of God's commandments about what is appropriate to eat.
God has always cared what we eat. From Eden to Revelation, even in Acts 15, the stuff we put in our mouths has been at the very center of obedience to God's commands.
