The Greek and Roman cultures were full of idols and temples where people would offer sacrifices, including meat. People would buy and eat this meat at the temples.
Paul answered a question about this. The Corinthian congregation asking if it was ok to eat this meat since the idols weren’t really gods. He said sure as long as it doesn’t cause someone with a weak conscience to sin.
According to Paul, some have a weak conscience and others a strong one. How weak or how strong depends on how I continually act with the revealed knowledge of God; his character, his will, his design, his Word, his Son, and his Spirit. (Romans 1:21-25, Ephesians 4:17-19, 1 Timathy 4:2-5) Paul said even Christians can have a weak conscience if their understanding is incorrect.
As I grow in Christ and do the right things my conscience becomes stronger. Truly I have grown a lot and needed to change my thoughts and actions through the years. Growing in conscience isn’t easy for my sinful nature is always there. God writes his word on my heart through the Holy Spirit, help to my conscience. (Romans 7:15-22)
God did not create man with a conscience. Adam and Eve knew God. Since they had not sinned, they did not need to determine if what they were doing had been right or wrong. Yet God told Adam, “You must not eat from the tree of the knowledge of good and evil.” When he and his wife ate from the forbidden tree they gained a conscience and passed it down to all. They learned good and evil. They gained a conscience.
Love for others is more important than my rights. God has taught me a lot from years of studying the Bible, prayer, living by faith, and his insights. I see others have a wrong understanding and thus have a weak consciousness. I should not cause them to stumble with my rights.
