The thing with sick people visiting Lourdes and other holy shrines for healing is that the numbers work against them. For instance, in this video religious claim is that out of all the millions of people visiting Lourdes for many years there has been 66 "confirmed healings", which, let's face it, doesn't make any positive impression at all.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
