Romans 14:14
As one who is in [fellowship with] the Lord Jesus, I am fully convinced that nothing in itself is [ceremonially] unclean. But to the person who considers something [ceremonially] unclean, it then becomes unclean to him.
1 Corinthians 8:7
However, not every person knows this [truth]. For some people have been so used to an idol all this time that they still think of the idol [as a reality] when eating food that has been sacrificed to it. And their weak conscience becomes polluted. [Note: These people cannot seem to shake off the idea that somehow the idol is real, so feel guilty of wrongdoing when eating food sacrificed to it].
Romans 14:2
One person has enough faith that allows him to eat anything [i.e., without it bothering his conscience that the food, such as animal meat, was used in an idolatrous worship ceremony]. But the weak person can eat only vegetables [conscientiously].
Romans 14:20
Do not destroy God's work [i.e., someone's life] for the sake of something to eat. All foods are truly clean [ceremonially]; however, it is wrong for a person to eat something when it causes another person to fall [away from God].
Acts 10:14-15
But Peter answered, "No, Lord, I cannot. I have never eaten any such ordinary or [ceremonially] unfit creatures."
Acts 10:28
And he said to them, "You people know how unlawful it is for a Jew to associate with, or even go near a person from another [i.e., non-Jewish] country, and yet God showed me that I should not consider any person ordinary or [ceremonially] unacceptable.
1 Corinthians 8:10
For if someone with a weak conscience sees you, who have [correct] knowledge [in this matter], eating in an idol's temple, will he not be encouraged to eat food sacrificed to idols?
Acts 11:8-9
But I said, 'O no, Lord, for I have never even tasted anything ordinary or [ceremonially] unfit [for Jews to eat].'
Romans 14:23
But the person who has doubts about eating [a certain food] is self-condemned if he [goes ahead and] eats it, because his action is not based on faith [i.e., if he lacks the conviction that he is doing what is right]. And whatever is not done with such a conviction is a sin.
1 Corinthians 10:25
Eat whatever is sold in the [public] meat markets, without asking any questions [about it] for [your] conscience' sake [i.e., do not inquire about the previous use of the food you buy, because you might discover something about it that would make you feel guilty of wrongdoing if you ate it].
1 Timothy 4:4
For everything created by God is permitted [to be eaten] and nothing should be refused, if it is received with gratitude,
Titus 1:15
Everything is pure [i.e., ceremonially acceptable] to the person who is pure [i.e., who has been cleansed by the blood of Christ], but to those who are [spiritually] corrupt, and do not believe [in Christ], nothing is pure, but both their minds and consciences are corrupted. [Note: This statement was intended to remove the physical restrictions imposed by the law of Moses].
