Anti-spiritual links

The following are Catholic sites, seemingly unaware of their madness and/or unafraid of displaying it

St. John Vianney Sermons (Cure d'Ars) - sermon on Purgatory (his sermon on the Last Judgement, in French, is quite scary ; I don't know if there is an English version) - more - Other catholic pamphlets
Writings by St John Henry Newman
A claim of near death experience in support of a madly, ridiculously sectarian form of Catholicism (I received this link from a Catholic debater, yes yes)
The Analyst; or, a Discourse Addressed to an Infidel Mathematician.
Faustina's diary, story of her masochist relationship with a sadist ghost claiming to be "Jesus", can be read in different sites. In this game, the goal for the ghost is to invent and tell her the most insane and ridiculous lies possible to see how far he can fool her; while the goal for her is to train herself to keep believing these lies at all cost, no matter how absurd or ridiculous they may be. In spite of its fundamentally tragic, insane and miserable nature, this story (of which I only read a little part) gave me one of the biggest laughs of my life. Very mixed feelings.

Of course not all Christians are insane, at least not in all topics

I admit that is hard to find, but sometimes I happen to find Christians with a sane way of thinking... at least in some topics, and apart from how a number of them turn out to deconvert. Here is are rare examples of wise thoughts by some Christians (we may say, these thoughts are wise rather because they are not really Christian but oppose the more usual trends of Christianity, but...). I wish so much to see more Christians as relatively wise as this:

"My definition of 'pro-life' ".
