I went to Catholic schools. The RCC has always been a mix of rational science and theism. In the 90s the position on evolution became that it is part of god's plan. Other denominations have followed to a degree.
And for the century prior to the 1990's, the RCC irrationally attacked the science of evolution, using all the same tactics as F.E., anti-vaxxers, and other crazy woo nonsense. The fact that they decided to change their strategy to stem the rapid loss of adherents (and revenue) doesn't make them any less peddlers of woo nonsense or enemies of reason. Also, there change wasn't to really accept the science of evolution. The idea that God guided evolution is simply a form of artificial goal-directed genetic manipulation and selection, where God is analogous to Monsanto. As such, it is logically incompatible the scientific theory of natural evolution where speciation occurs via processes of random variation and happenstance selection depending upon what happens to work well in that context at that time. Theistic evolution also promotes the anti-science notion of evolution as progressive and linear. The type of theistically controlled evolution that the RCC promotes only accepts the most vague broad brush notions that organisms have changed over time, but it promotes the rampant distortions and misconceptions about how evolution actually works and how it historically unfolded.
Pseudo science is science that can be proven wrong. The Christian creation myth is neither provable or disprovable.
Creationism is logically at odds with science (as is theistic-evolution). If creationism is viewed as nothing but fictional allegory, then of course it is neutral to science b/c it then it isn't making any claims that are relevant for objective reality. But the RCC, only treats some of the creation story as myth and some as fact, and that makes it incompatible with science and reason.
In addition, the creation story, and any claim that presumes the existence of an immaterial mind is against the absolute mountain of science strongly showing that everything we concieve of as "mind" is a byproduct of particular, rare organizations of matter. IOW, science strongly refutes the theory of God that the RCC and almost every monotheist believes in.
Reason is not neutral on God. God is among the most unreasonable and implausible notions ever conceived. Thus, anyone or organization that promotes the idea that God exist is engaging in anti-reason and anti-science, even moreso than the craziest woo pseudo-science believer you can imagine.
From a certain perspective the BB Theory could be considered woo, it is entirely speculative. There is no way to demonstrate it. We accept it generally because it is based on science we can demonstrate and see today.
Accepting theories because they are logically supported by the science we can demonstrate today is called science, not woo. Being able to directly observe a theorized event unfold is not a requirement for something to be science. Reasoning about what the observable evidence logically implies about what was most likely to have happened in at a particular point in time is called evidence-based reasoning, not "speculation".
I would not label Christianity pseudo science. I call it mysticism and the supernatural. That encompasses a lot.
The RCC and most theists do engage in forms of pseudo-science to try and make their beliefs seem less anti-science and irrational than they inherently are. However, the religions are not in themselves psuedo-science b/c in principle one could just completely ignore science and not even try to appear rational, as Martin Luther the founder of Protestantism advocated. But any theistic religion (or one that promotes an afterlife) is inherently anti-science in that they deny the relevant science that supports ideas which are logically incompatible with their preferred beliefs.
Religion usually involves a higher power or sprit. Pseudo science does not.
The notions of a spirit or higher power are more irrational, anti-science, and implausible than the vast majority of non-religious pseudo-science claims. Also, psuedo-science as a method of dishonest rhetoric to hide the irrational faith-based nature of one's beliefs is often engaged by many religious leaders and followers. So, that makes some pseudo-science an aspect of most religions.
