Yes, you’re approaching my question. What does it mean to be “spiritually begotten”?
Since God is a spirit, what he begets is spirit. God does not have a body nor is he composed out of matter. So again, since God is a spirit, the Son he begets is accomplished in a spiritual manner unlike the procreation of human beings in which the material bodies of the man and woman are united.
The procession of the Son of God from God the Father proceeds from the intellect of the Father. The intellect is a spiritual power that together with the spiritual will humans and angels also possess and in which humans and angels are principally made in the image of God. In the beginning of the gospel of St John, the only begotten Son of God is called the Word of God. A word is something that is conceived by the intellect, it pertains to knowledge and so Christ is also called the Wisdom of God. God the Father begets or generates the Son by his act of understanding which is a spiritual act. The Holy Spirit proceeds from the will of God the Father and God the Son, from their mutual love for one another. This is also a spiritual act.
Also, as eternal, then is being begotten a continuous state?
