“You made all the delicate, inner parts of my body and knit me together in my mother’s womb . . .. You watched me as I was being formed in utter seclusion, as I was woven together in the dark of the womb. “Psalm 139:13, 15.”
“I tell you, unless you repent and become as humble as little children, you will in no way enter into the Kingdom of Heaven. Whoever humbles themselves as this little child will be the greatest in the Kingdom of Heaven. Whoever receives one little child in my name receives me” (Matthew 18:1 to 5).
These bible passages show that having a baby should only be done naturally or done in another method such as adoption because if other forms of fertilisation occurred then it wouldn’t be seen as natural to the church and it isn’t accepted and wouldn’t be accepted by God.
This link is what the Catholic Church believes about IVF, it was released on the 12th of December 2008. In the church document in the link above it states that couples must be married, conception must occur through normal intercourse and the embryo must be treated with respect meaning that no other forms of fertilisation should occur other than natural. IVF does not follow these three steps making them wrong and not allowed within the Catholic Church. The Catholic Church also doesn’t like it because embryos might be thrown away. They believe that couples that are infertile should not partake in IVF but to consider adoption if they wish to still have children.
