Well, it's not supposed to be what "the Church" says, but it's true that the Church (as an institution) has really clouded things, and made itself the center of the Christian life. The original "church" was people meeting in the homes, and overseers watching to make sure the truth of Christ was taught. The later institution people judge "Christianity" on was a great corruption.In Marxism we do what Mao says. In Christianity we do what the church says under the justification of such actions representing God's will.
Again; that's only when all the baggage of the corrupt institution is added. An institution had no [divine] business persecuting people for saying the world was round, or not at the center of the universe, when Christ and other scripture authors never stated such, or made it an underlying principle. (or authorized the sword or power of the state to enforce the truth, for that matter either).The bottom line is, religion is incompatible with critical thinking because it insists on acceptance of instructions by default. Growth of civilization is impossible because of this as such a regime precludes new ideas from being propounded. Religious thinkers who have propounded ideas behaved in a decidedly irreligious fashion.
