Everything that the article discussed is rooted in scripture as described fully in the Catechism of the Catholic Church. You should read it sometime, it is the ONLY fully articulated and fully scritptural explanation of Christian doctrine (not Catholic, but Christian) that I am aware of.
This article was merely a logical dissection of the arguments of a few old hippie nuns who are still fighting the Vietnam war and protesting Richard Nixon.
Sad that you need scripture “described” to you, when you could just read it yourself.
