Sorry to disappoint you Manfred, these things have been discussed at great length on the forum and if you want to believe that Jesus Christ is God, that the Holy Spirit is part of a triune God then that's entirely up to you, but you must respect that not everyone shares your belief.
Also i must point out your inaccuracy, as is so often the case when one quotes from a third party, they clearly do not understand, nor have taken the time to actually try to ascertain what our beliefs are and why we profess them, for we do not profess that by abstaining from certain foods or liquids that it shall make us any more 'holy', than he next man, sorry to disappoint, but i do not know where you sourced you information, for it is clearly erroneous.
(Romans 14:17-18) . . .For the kingdom of God does not mean eating and drinking, but means righteousness and peace and joy with holy spirit. For he who in this regard slaves for Christ is acceptable to God and has approval with men.
here is just one verse which highlights your errm 'inaccuracy', (we shall not call it a lie quite yet) ,
firstly we can see that Paul states adherence to a certain ritualistic code of what one eats and what one does not eat has practically no value in regard to the Kingdom of God (you do know what the Kingdom of God is , dont you?), for it is a matter of conscience.
i had also better clarify, why fasting may be acceptable, on an individual basis, for we hold that if anyone feels the necessity to fast, simply to have clarity of thought, not that it shall make a person more Holy, a person may wish, based on an individual basis and concerning the dictates on conscience, to fast. There is of course a Biblical precedence for this.
Lastly this verse shows the absurdity of accepting the Hoy Spirit as a personage, for quite clearly it is the exercise of Gods inanimate force , which causes a person, in this instance, to experience peace and joy.
(Galatians 5:22-24) . . .On the other hand, the fruitage of the spirit is love, joy, peace, long-suffering, kindness, goodness, faith, mildness, self-control. Against such things there is no law.
