The Father and the Son are Parents of the Holy Spirit, if many churches are correct. If many churches are correct, The Trinity is a Family-- two Parents and a Progeny, just like a human family. (Humans are made in the "image" and "likeness" of God according to Genesis 1:26) In the Book of Job which is part of the bible,God is compared to a father and also a mother with a womb. "From whose womb comes the ice? Who gives birth to the frost from the heavens"--Job 38:29. Because God can also be thought of like a mother (Isaiah 42:14,Isaiah 66:13,Matthew 23:37, Psalm 131:2, Catechism of the Catholic Church 2nd edition paragraph 239), all three roles (father,mother,progeny) in a basic human family are filled in the Trinity. Saying that the "Father and the Son are the Parents of the Holy Spirit" is simply another way of saying that the Holy Spirit "proceeds from the Father and the Son" which has been official Catholic Church teaching for centuries. According to the Catholic Church, the Son is begotten from the Father. If this is correct, the Father is the father(Parent) of the Son. According to the Church, the Holy Spirit proceeds from the Father and the Son.If this is correct, the Father and the Son are the Parents of the Holy Spirit. According to the Catechism of the Catholic Church (second edition)paragraph 246, the Holy Spirit's "nature and subsistence" is "at once(simul) from the Father and the Son." If the Church recognizes Mary as mother(parent) of God even if Mary isn't the first source of Christ's humanity(God is the first source of everything),then the Son can also be rightly called a Parent of God(the Holy Spirit).If the Catholic Church is correct, the Father is the Principle-parent and the Son is the begotten-Parent. The scriptures are vague if the Holy Spirit is the 3rd or 2nd Person of the Trinity--whichever of these is true,the First Person and the Second Person may be the Parents of the Third.
