There’s no comparison:
- Science is not only competent to pronounce on dinosaurs - certain branches of it (such as palaeontology) would be remiss not to do so
- Science has no competence in matters of Eucharistic theology, because the Eucharistic conversion is not a scientific phenomenon; it is a metaphysical one
Which is why the analogy fails.
Bad science is bad theology - it gives a false account of the work of God in creation. The Church has eveything to fear from the kind of theology that distorts the sciences in the interests of faith, & nothing to fear from unrestricted, free & honest scientific enquiry. A faith that requires lies & deceit & fictions & bad exegesis of the Holy Bible is a faith with rotten foundations; it’s not faith at all, but a form of unbelief. For real faith is not afraid of scientific, or any other, research - it cannot tolerate falsehoods, but needs truth, from whatever quarter, because it trusts God to be true to Himself.
Unlike Fundamentalism.
