I appreciate what you’re saying, and I think it’s important to hear. In writing with such wry and caustic humour, you’re able to really effectively reveal the absurdity of what’s happened. There is a difference, however, between parody and ridicule. At points your sarcasm (“one third time for logical conjecture,” etc.) becomes quite harsh and implies that the religious view denies logic and reasoning wholesale.
You’re dealing with something that, more than being a “precious belief” per se, is an important part of many people’s identity. Many define themselves, not just peripherally, but primarily as “Christians.” Attacking that belief system without at least giving it some hint of respect or sensitivity is akin to mocking a person’s chosen lifestyle, personality, or preferences as not just different but illogical and wrong. You can’t in one section write ironically about the deductive demerits of believing in written scripture as a priori truth and then claim to avoid attacking the very heart of a person’s belief system and philosophical identity. You have literally brought the very basis of not only Christian teaching but religious belief in general into question, and in a fairly patronising and uncompromising way.
I’m not asking you to “present both sides” or any equally bullshit measure. But I am asking you to be empathetic. When criticising the core of a person’s self-identity (what they believe in), it’s important to be a little more humane.
