7 Ye hypocrites, well did Esaias prophesy of you, saying,
8 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.
9 But in vain they do worship me, teaching for doctrines the commandments of men.
10 And he called the multitude, and said unto them, Hear, and understand:
11 Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
12 Then came his disciples, and said unto him, Knowest thou that the Pharisees were offended, after they heard this saying?
13 But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up.
14 Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.
15 Then answered Peter and said unto him, Declare unto us this parable.
16 And Jesus said, Are ye also yet without understanding?
17 Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?
18 But those things which proceed out of the mouth come forth from the heart; and they defile the man.
19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:
20 These are the things which defile a man: but to eat with unwashen hands defileth not a man.
The LDS church teaches that if you eat or drink certain things such as wine, coffee and tea, you will distance yourself from God and lose the influence of the Holy Ghost. Doing so makes it to where a member is no longer in good standing in the church and, in many cases, cannot participate in communion or holding positions in the church. It always keeps them from going to the Temple which is only reserved for those members who follow all of the commandments of God as revealed by his modern prophets for “no unclean thing can dwell with God”.
20 And that no unclean thing shall be permitted to come into thy house to pollute it;
21 And when thy people transgress, any of them, they may speedily repent and return unto thee, and find favor in thy sight, and be restored to the blessings which thou hast ordained to be poured out upon those who shall reverence thee in thy house.
If you contrast that idea with what Jesus taught in the New Testament, you see something completely different. You see a God that does not care what you put into your body but rather, what you let come out of it. He taught that a person’s heart, mind and soul were more important than a glass of wine. Shoot, Noah got drunk on more than one occasion but that did not stop God from calling him to be a prophet because he knew what was in his heart.
Why then does Mormonism put so much credence in the WoW? I think it is a very easy way to “measure” a person’s loyalty to the church and control its members through social pressure. The Pharisees did the same thing and in return they received a rebuking which I think Jesus would give to the LDS leaders today if he were here.
