Romans 14:15

For if because of meat thy brother is grieved, thou walkest no longer in love. Destroy not with thy meat him for whom Christ died.

Starting from verse 13 Paul is addressing the meat-eater. He was right, he had. right to eat meat, but that right could be abused!

The following verses will express the same truth as addressed in 1 Corinthians 8:1 /10. In certain situations, eating meat, and espeically that sacrificed to idols, could do harm to another.

Here is another verse that proves that the items under consideration are 'indifferent in themselves'. But for those that agrue Romans 14:1 is dealing with or cover's matters of sin and error. Can sin become more sinful? Whatever is under consideration here is right, and in certain settings wrong. But those things inherently sinful are WRONG REGARDLESS OF THE CIRCUMSTANCES!
