Regarding Miracles.

*If you are to believe all of those fundamentalist, right-wing, evangelist Christians, there are thousands of God-inspired supernatural miracles recorded every year, especially in faith healings and related. If you add to those claims those supernatural miracles accepted as genuine bona-fide true miracles by the Catholic Church, then there should be absolutely no doubt that supernatural miracles were as real and as well documented as gravity. Alas, there's not so much as even one miracle ever observed and verified and written up in a peer-reviewed scientific journal and undisputedly accepted by the scientific community as proof of the supernatural. I think that alone pretty much sums up the validity of any supernatural miracle attributed to God.

*Why can't an all-powerful God who answers prayers and who performs miracles recreate an amputee's missing limb? Why? Because there is no God, that's why!

*For the Catholic Church to declare some event as a bona-fide miracle (i.e. Fatima, October 1917), well that's akin to a true believer in Bigfoot or the Yeti declaring that a photograph of an eroded 'primate' footprint in the snow is absolute proof of same. True believers will obviously endorse events that reflect evidence for their true belief.

*If you believe in prayer, then why would you bother with health insurance and visits to the doctor?

*Miracles are the required ways and means on the assumption that God works at cross purposes to natural causality (which He Himself established) rather than through natural causations - which under the circumstances is a rather irrational thing to do.

*Take two aspirin and then pray that your headache goes away!

*If there is an all-powerful God then there is no need for miracles on the grounds that prevention is better than cure. And if there is an all-knowing God then there is no need for your prayers.

*Even if your prayer is answered, that doesn't mean of necessity that God answered it. Perhaps it was a magical pixie - how could you tell?

*I prayed to God to never answer any prayer of mine ever again, and it worked, so obviously prayer works!

*If you pray for what God has already decided He doesn't want to happen, there's no point in praying. If you pray for what God has already decided He does want to happen then there's no point in praying. In other words, if God has a master / divine plan and God is all-knowing, then prayer is useless. Praying is not going to change God's all-knowing and made up mind.

*If you pray to your god (or God), you are basically telling Him that he has screwed things up and so you’re going to tell Him, via your prayer, how to set things to rights.
