I think The One wrong action that confuses more people about religion, spirituality and God than anything else is to rely exclusively on what other humans think and say (including what the clergy says...).
We may want to talk to others we trust to check-in with their opinions but we must never forget that it is opinion.
Yes, Truth is Truth, no doubt. Yet, humans are humans with our well-known ability to refract the Truth through the lens of our egos into partial truths.
We must face God ourselves to find the Truth then celebrate the muti-faceted expression of it with our fellow humans!
I find the following quote from Reality particularly powerful:
certitude, must cleanse themselves of all that is earthly—their ears
from idle talk, their minds from vain imaginings, their hearts from
worldly affections, their eyes from that which perisheth. They
should put their trust in God, and, holding fast unto Him, follow in
His way. Then will they be made worthy of the effulgent glories of
the sun of divine knowledge and understanding, and become the
recipients of a grace that is infinite and unseen, inasmuch as man
can never hope to attain unto the knowledge of the All-Glorious, can
never quaff from the stream of divine knowledge and wisdom, can
never enter the abode of immortality, nor partake of the cup of
divine nearness and favour, unless and until he ceases to regard the
words and deeds of mortal men as a standard for the true
understanding and recognition of God and His Prophets."
