Does not seem to be biblical. At least to me.
Matthew 15:11 King James Version (KJV)
>11 Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
Romans 14:2-3 King James Version (KJV)
>2 For one believeth that he may eat all things: another, who is weak, eateth herbs.
>3 Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him
Romans 14:13-15 King James Version (KJV)
>13 Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
>14 I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
>15 But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died.
Romans 14:19-23 King James Version (KJV)
>19 Let us therefore follow after the things which make for peace, and things wherewith one may edify another.
>20 For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.
>21 It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
>22 Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth.
>23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
