You do know that is about fasting right?
Romans 14 NKJV
14 Receive one who is weak in the faith,
but not to disputes over doubtful things. 2 For one believes he may eat all things, but he who is weak eats
only vegetables. 3 Let not him who eats despise him who does not eat, and let not him who does not eat judge him who eats; for God has received him. 4 Who are you to judge another’s servant? To his own master he stands or falls. Indeed, he will be made to stand, for God is able to make him stand.
5 One person esteems
one day above another; another esteems every day
alike. Let each be fully convinced in his own mind. 6 He who observes the day, observes
it to the Lord; " and he who does not observe the day, to the Lord he does not observe
it. He who eats, eats to the Lord, for he gives God thanks; and he who does not eat, to the Lord he does not eat, and gives God thanks.
As you can see the passage mentions eating and days. Nowhere does is specifically say fasting, but certainly, that can also apply. If you want to be specific it's about eating only vegetables which some people may view as vegetarianism. The point of the passage is about not judging or disputing doubtful things in regards to eating and days.
Matthew 22:37-40 NKJV
37 Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ 38 This is
the first and great commandment. 39 And
the second
is like it: ‘You shall love your neighbor as yourself.’ 40 On these two commandments hang all the Law and the Prophets.”
I think most of us here are using the Bible (I am using the New King James version) so I'm not sure why you keep telling us it is also in the Torah. Obviously there will be some cross over, but I don't see how that is relevant to the discussion.
