if Christianity imbued its genuine followers with the ability to supernaturally grasp a meaning that is out of reach for any ordinary person, then Christians throughout history would exhibit an inexplicable ability to arrive at the same result in their exegesis of scripture.
what we see is not a flock of enlightened carrying the torch of revelation to the dark places, but politics, power plays, and military interventions.
The Reformation made the Scriptures available to everyone who could read, sparking literacy and democratization - and also the fragmentation of Christianity into a gazillion of discordant "denominations" who cannot agree on the meaning of a single verse.
Jane, even we who are real Christians are not perfect. And we are not controlled and cloned by some few dictators who make us all say and think the exact same thing. And there are false ones who come up with many different wrong items.
We grow to know things, like a child needs to develop before he or she even can know what he or she needs to learn. A baby's young body does not have very good unity of behavior. And, like a growing child, we grow into our unity as the body of Jesus.
However, the unity is not only in outward say-so and behavior. But we find our true unity in becoming gentle and humble and all-caring. And we become pleasing to our Father in His love's "gentle and quiet spirit" >
"rather let it be the hidden person of the heart, with the incorruptible beauty of a gentle and quiet spirit, which is very precious in the sight of God." (1 Peter 3:4)
Notice how the beauty of God's gentle and quiet love is "incorruptible". No nasty messing things can degrade us, as much as we are in the almighty immunity of God's love. This is included in being saved > being safe emotionally >
"There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love." (1 John 4:18)
As we become changed into the image of Jesus, we grow in being safe from various fears and worries and the personality torments which are rooted in fears of different sorts.
So, true unity is in God's love, not only in having the same ideas. Tyrants seek to make all their people the same, so they can control them as a group. But Jesus is not a tyrant. So, yes there are groups who call themselves Christian, but who are isolating people with their ideas, then controlling those groups for what they want. And yes plenty of Satan's people are into this counterfeit stuff. Counterfeits are used to try to make the real thing look bad.
There are people who criticize "God" and "Christianity", but they really are talking about Satan and how things work in his evil kingdom.
But salvation in Jesus is not about quantity of people or copy-catting the same beliefs and behavior, but there is the quality of unity in "the incorruptible beauty of a gentle and quiet spirit, which is very precious in the sight of God." (in 1 Peter 3:4) And we have our true unity in how we relate > "with all lowliness and gentleness, with longsuffering, bearing with one another in love," (Ephesians 4:2) "submitting to one another in the fear of God." Ephesians 5:21) And we discover our unity in obeying the theocracy of how our Heavenly Father personally rules each of us in His very own peace in our hearts > Colossians 3:15.
So, yes, there is Satan's clever trick of having people call attention to all that is wrong, so our attention is elsewhere!! And so, salvation includes being turned "from the power of Satan to God" (in Acts 26:18). Only God is able to make the real change, and not only outward change of outward religious conforming.
