Hi CG. Have you had your covid shot yet? I’m up in arms about it because both my wife and I have numerous risk factors. Between a rock and a hard place. Damned if I do and damned if I don’t.
Regarding Sources that are reliable.
Baha’is clearly have a few Divine Sources to turn to for guidance.
Abdul-Baha
In His Will, Baha’u’llah appoints Abdul-Baha as His Successor.
When the ocean of My presence hath ebbed and the Book of My Revelation is ended, turn your faces toward Him Whom God hath purposed, Who hath branched from this Ancient Root.’ The object of this sacred verse is none other except the Most Mighty Branch (‘Abdu'l-Bahá)
Regarding Interpretation
And, again, in the Kitáb-i-Aqdas, we read:
“When the Mystic Dove will have winged its flight from its Sanctuary of Praise and sought its far- off goal, its hidden habitation, refer ye whatsoever ye understand not in the Book to Him Who hath branched from this mighty Stock.”
Baha’u’llah says Abdul-Baha is a most great Favor to Humanity
Render thanks unto God, O people, for His appearance; for verily He is the most great Favor unto you, the most perfect bounty upon you; and through Him every mouldering bone is quickened. Whoso turneth towards Him hath turned towards God..
Abdul-Bahá’s knowledge and wisdom according to Baha’u’llah
My glory, the ocean of My loving-kindness, the sun of My bounty, the heaven of My mercy rest upon Thee. We pray God to illumine the world through Thy knowledge and wisdom.
Shoghi Effendi
Then in the Will of Abdul-Baha regarding Shoghi Effendi and 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.
So the authority with which Abdul-Baha and Shoghi Effendi has been invested is very clear, definite and powerful not iffy or minor.
And there is much Divine guidance from the sum of all these sources on the topics you mentioned but not everything. It is probably best we offer that guidance but for those topics we don’t have enough information about just to perhaps mention we don’t know.
