Can Christians eat it?
Yes, Christians can eat what ever they wishes for two reasons. First - we are free from all things, John 8:36; Romans 8:1. Second - Jewish dietary Law has never been relevant to gentiles.
Nonetheless, some people believe that God forbids eat pig meat, and some other food, because it is said - "And the pig, though it has a divided hoof, does not chew the cud; it is unclean for you. You must not eat their meat or touch their carcasses; they are unclean for you" (Leviticus 11:7-8; Deuteronomy 14:8).
All Law was given to the Israelites. Ten Commandments particularly indicate and show how sinful humans are; and that they by themselves are not able to fulfil, or keep, even the smallest commandment of all. All Commandments point to Christ, and that without Him man is lost, already stand condemned and without any hope in this world, because is a subject to the god of this world. All Commandments point that without Christ (taken together all world's religions) we are not able to approach God, receive forgiveness and wherewith all what we do, believe and follow is nothing at all.
In the NT we can read that God gave Peter vision in which He told, that all God's made creation are clean. In this vision God told Peter: "Do not call anything impure that God has made clean" (Acts 10:15). All foods are clean – pig, crab, shrimp and all other foods now are clean. Gentiles now are clean too!!! Thanks to our heavenly Father through the our Saviour Jesus Christ!
But "to the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted" (Titus 1:15).
God said: "do not call something (nothing) unclean if God has made it clean" (Acts 10:15).
So, obey God and do not call unclean or forbidden. Instead receive everything with joy and be thankful for everything.
But we must be careful to judge in showing our freedom to those, who have week faith (1 Corinthians 8:9).
"Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in your brother's way. As one who is in the Lord Jesus, I am fully convinced that no food is unclean in itself. But if anyone regards something as unclean, then for him it is unclean. If your brother is distressed because of what you eat, you are no longer acting in love. Do not by your eating destroy your brother for whom Christ died. Do not allow what you consider good to be spoken of as evil. For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, because anyone who serves Christ in this way is pleasing to God and approved by men. Let us therefore make every effort to do what leads to peace and to mutual edification. Do not destroy the work of God for the sake of food. All food is clean, but it is wrong for a man to eat anything that causes someone else to stumble. It is better not to eat meat or drink wine or to do anything else that will cause your brother to fall. So whatever you believe about these things keep between yourself and God. Blessed is the man who does not condemn himself by what he approves. But the man who has doubts is condemned if he eats, because his eating is not from faith; and everything that does not come from faith is sin" (Romans 14:13-23).
Because: "If we live, we live to the Lord; and if we die, we die to the Lord. So, whether we live or die, we belong to the Lord. For this very reason, Christ died and returned to life so that He might be the LORD of both the dead and the living. You, then, why do you judge your brother? Or why do you look down on your brother? For we will all stand before God's judgment seat. It is written: " 'As surely as I live,' says the LORD, 'every knee will bow before me; every tongue will confess to GOD.' " So then, each of us will give an account of himself to GOD." (Romans 14:8:12).
So, we may eat what ever we wish, but anyway, keep in mind that sometimes things can be harmful. Paul explained it very clearly: "I have the right to do anything," you say - but not everything is beneficial. "I have the right to do anything" - but not everything is constructive. No one should seek their own good, but the good of others. Eat anything sold in the meat market without raising questions of conscience, for, "The earth is the LORD's, and everything in it" (1 Corinthians 10:23-26). You can eat anything you wish, but if you eat something which can cause you get sick, than better do not eat.
"If an unbeliever invites you to a meal and you want to go, eat whatever is put before you without raising questions of conscience. But if someone says to you, "This has been offered in sacrifice," then do not eat it, both for the sake of the one who told you and for the sake of conscience. I am referring to the other person's conscience, not yours. For why is my freedom being judged by another's conscience? If I take part in the meal with thankfulness, why am I denounced because of something I thank God for? So whether you eat or drink or whatever you do, do it all for the glory of God. Do not cause anyone to stumble, whether Jews, Greeks or the church of God" (1 Corinthians 27-32).
See, you, child of God, you are the most free person of all! You can eat and drink what ever your wishes are. Just take into account and always consider everything what Jesus taught, and all things do for the glory of God the Father of your Saviour Messiah. Every time when you have doubts, go to the Word of God and seek for answers.
"It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery" (Galatians 5:1; John 8:36).
"Live as free people, but do not use your freedom as a cover-up for evil;
live as God's slaves. Show proper respect to everyone, love the family of believers,
fear God, honor the emperor"
(1 Peter 2:16-17).
