The Church does not teach about science. But the Church does not object to (legitimate) science.
For example, science tells us that a distinct human organism begins to live at the moment of conception. The Church has absolutely no problem whatsoever with that teaching.
Most Catholics on this Forum accept the Big Bang theory as the causal mechanism of creation (according to a
poll I started which is currently running). It does not require “special pleading and pseudorationalizing” (whatever that means) for Catholics to accept this scientific theory. Catholics believe God created the universe out of nothing, and most see no conflict with a scientific theory that the universe was created from a zero-dimensional singularity with no size but infinite mass, at a “time” when neither time nor space even existed. When this idea was first proposed by a Catholic priest (Fr. Georges Lemaître), the scientific community mocked it as an attempt to impose religion on science. The old “steady-state” scientists refused to accept the idea of a creation event on the mere basis that it seemed too Biblical. A priest brought science to them, and no scientist believes in the steady-state theory today. Ironically, more scientists (approx 100%) believe in the Big Bang theory than Catholics on this Forum (75%), and the idea came from a Catholic priest.
