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 14:14

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.

Romans 14:22-23

Therefore, whatever you believe about this matter should be held between you and God. That person is happy who does not condemn himself for practicing something he believes is right.

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].

Galatians 2:12

For, before certain [leaders] came from James [i.e., Jesus' brother, a leader of the Jerusalem church, See Acts 12:17; 15:13-22], he had eaten [a social meal] with some Gentiles. But when these men came, he abruptly discontinued this practice out of fear of the circumcised ones [i.e., out of concern for what the Jews would think of him].

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].

Hebrews 9:10

since, with foods and drinks and various [ceremonial] washings, they are only outward regulations imposed until the time when everything would be made right [i.e., under the New Agreement].

Hebrews 13:9

Do not continue to be swept off your course by all kinds of strange teachings. For it is good for your hearts to be strengthened by God's unearned favor [upon you] and not by [keeping regulations about] foods, which do not benefit those who observe them.
