By attacking the institutions while appearing to follow the Bahá'í Faith, you are really running afoul of the Covenant here, and Jonah has stated such posts are not welcome here. If someone claims to be a Bahá'í and yet claim to know better than our officially appointed Universal House of Justice--whose legitimacy as an infallibly-guided Successor-Institution was most clearly delineated in our Writings (see below), the only result will be divisions, with the assumption being that the opinions of so-called scholars should trump those actions of our legitimately appointed Successorship.
As you seem to speak in favor of Shoghi Effendi, consider that the document which also appointed Him also granted the same infallibility to the Universal House of Justice:
The sacred and youthful branch, the Guardian of the Cause of God, as well as the Universal House of Justice to be universally elected and established, are both under the care and protection of the Abhá Beauty, under the shelter and unerring guidance of the Exalted One (may my life be offered up for them both). Whatsoever they decide is of God. Whoso obeyeth him not, neither obeyeth them, hath not obeyed God; whoso rebelleth against him and against them hath rebelled against God; whoso opposeth him hath opposed God; whoso contendeth with them hath contended with God; whoso disputeth with him hath disputed with God; whoso denieth him hath denied God; whoso disbelieveth in him hath disbelieved in God; whoso deviateth, separateth himself and turneth aside from him hath in truth deviated, separated himself and turned aside from God. May the wrath, the fierce indignation, the vengeance of God rest upon him!
(Will and Testament of 'Abdu'l-Bahá, p. 11)
And as far as "Summons of the Lord of Hosts", here is a letter in which Shoghi Effendi (original in English) used that term: "I direct my impassioned appeal to obey, as befits His warriors, the summons of the Lord of Hosts". He also used, in a translation contained in The World Order of Bahá'u'lláh, the term "Tabernacle of Unity": ""The Tabernacle of Unity," Bahá'u'lláh proclaims in His message to all mankind, "has been raised..."
Regarding placing blame on the individuals of the House of Justice, as should be evident by a read of the Will and Testament--a document we as Bahá'ís were strongly advised by Shoghi Effendi to read, concerning the Universal House of Justice, "That which this body, whether unanimously or by a majority doth carry, that is verily the truth and the purpose of God Himself." (Will and Testament of 'Abdu'l-Bahá, p. 19) Their knowledge or lack of knowledge of Arabic or Persian is wholly irrelevant; they are not (through due elections) elected to themselves become translators.
As far as "forcing" people to take Ruhi, that is manifestly false. No one is obligated to participate, as their letters have stated.
As far as your concern with the reality of God, Shoghi Effendi stated:
"What is meant by a personal God is a God Who is conscious of His creation, Who has a Mind, a Will, a Purpose, and not, as many scientists and materialists believe, an unconscious and determined force operating in the universe. Such conception of the Diving Being, as the Supreme and ever present Reality in the world, is not anthropomorphic, for it transcends all human limitations and forms, and does by no means attempt to define the essence of Divinity which is obviously beyond any human comprehension. To say that God is a personal Reality does not mean that He has a physical form, or does in any way resemble a human being. To entertain such belief would be sheer blasphemy."
(From a letter written on behalf of Shoghi Effendi to an individual believer, April 21, 1939)
Any read of the Bahá'í Writings is going to need to take God intot account. Of course, as Bahá'u'lláh stated in the Hidden Words: "Ye shall be hindered from loving Me and souls shall be perturbed as they make mention of Me. For minds cannot grasp Me nor hearts contain Me."
So the question becomes, will we become like those who are so self-conscious of offending the present-day fashionable (yet ineffective) agnostic establishment that they fail to uphold what our Faith actually taught or do we humble ourselves and alter our own prejudices so that we can be more united with our fellow believers in (the unextinguishable belief in) God around the world and deliver Bahá'u'lláh's potent message in full to the waiting masses? At least with the mainstream Judaic and Islamic traditions (as well as Christian), God and such terminology you mention are not alien concepts. On the contrary, they are quite familiar.
We do, I believe, need to help people to remove some of the veils the term "God" conjures for many (whether it is in anthropomorphic conceptions or in terms of it seeming remote from our mystic selves), but it should be quite clear that we cannot remove the term!
If you wish to continue the discussion in a truth-seeking manner (e.g., by asking "well, what about this?"), then that is fine, but open hostility is, as Jonah has previously stated, not welcome on these boards.
