1 Corinthians 8:7, The Conscience Being Weak
William MacDonald said illustrated well, “For instance, as far as God is concerned, it is not wrong for a believer to eat pork. It would have been wrong for a Jew to do so in the OT, but a Christian is at perfect liberty to partake of such food. However, a Jew converted to Christianity might still have scruples about this. He might feel that it is wrong to eat a roast pork dinner. He is what the Bible calls a weak brother. It means that he is not living in the full enjoyment of his Christian liberty. Actually, as long as he thinks that it is wrong to eat pork, he would sin if he went ahead and did it. That is what is meant by the expression their conscience, being weak, is defiled.”
