I think the RCC is a house of cards, what does that have to do with Gen 1:1?
Why do you think the RCC is a house of cards? When are you expecting it to fall? A "house of cards" would indicate something "precarious" when, in fact, the Church is going on 2000-plus years of existence...
If you think the Catholic Church is a house of cards built on one verse of the Bible, so it follows that monotheism a house of cards built on the first chapter, first verse of Genesis.
