 He also hates marriage. He hates families because of the Trinity, which is a reflection of the family. I guess I should say it the other way around. The family is the reflection of the Trinity. Father, son, and their love spirates a new person, the Holy Spirit. Husband, wife, their love generates a new person, a baby, a child. So when Satan sees the family, he sees the Holy Trinity, and of course he hates the Trinity as well.
