Something is designed when it has been produced by reproduction – in other words, it has been designed. But we also see something else in God. He is not just one God in three divine Persons. These people also exist in relation to each other. When we try to express this father-son relationship in God, we say that the son is “begotten” by the father. In this way, Scripture refers to this divine relationship (see John 1:14–18; 3:16–18 for examples). When did that happen? Before creation, because, as John notes, the world was created by the Word [the Son]. Such an “action” of God takes place outside of His creation, outside of time itself. It is not an “event” closed by time, but a way of being in God Himself. This is why we say that the Son is “eternally begotten” by the Father. Honestly, there are many things we could say about these passages. They are very, very rich, but I would just like to make a few remarks.

First of all, if your English Bible is there, even though it says, “God loved the world so much that He gave His Only Begotten Son,” Greek is actually a little richer there, a little more nuanced than English. So the Greek word there is “God gave his monogenic Son.” Mono is just the word for it. Genēs comes from the verb gennaō and means to endure or witness. Thus, in Greek, it is literally said, “God gave his only begotten Son, that all who believe in him would not perish.” One of the reasons that is important is that he portrays Jesus as a unique type of Son. For example, if you look at the Old Testament—the Book of Job, for example, chapter 1—angels are called sons of God. But they are created sons of God, they are creatures, they have a beginning in time before which they did not exist. And even if you look at the New Testament – Romans 8 or Galatians 3 – people are called sons of God. In other words, Christians are called sons of God. When Paul says, “Those of you who have been baptized into Christ have become sons.” You now call Abba, Father, because we have been brought into the sonship of Christ, but we are adopted sons of God. And then people will always use the phrase “all men are children of God,” and that`s true, but what they mean by that is that God is like a Father because He is the source of their lives.

Just as a father gives life to his child, so God gives life to all men, and they are, in a sense, his children. Let us turn our attention to the other great mystery of our faith, the Incarnation. We have already established that Jesus was both the “Son of God” and the “Son of man.” John says it simply: “The Word became flesh and dwelt among us, and we saw his glory, the glory that belongs to him as the Only Begotten Son of the Father” (Jn 1:14). To fulfill God`s plan of salvation for all mankind, the Son voluntarily chose to become man. In doing so, it has been subjected to the same biological restrictions to which we are subject. He had to be born, and he had to die. He was born at a certain time, by a certain group of parents, in a certain place. The fact that he was born in this way was a historical event that could be studied in the archives of time. Some first thoughts: We usually talk about living beings as “conceived” or “born” and refer only to inanimate objects as they were made? Christ was/is, of course, a living being. But it seems pretty obvious.

Here, I think your quote from C.S. Lewis is true. Jesus is not a creature, he is not part of creation. Unlike the Arians, designed does not mean created. The other clauses (true God of the true God, one in the being with the Father, etc.) explain what begotten means as opposed to creation. In this sense, the fact that Jesus was conceived indicates him as God, not only as an agent of a God above, but as something that goes beyond what God had been, beyond God`s plan, and thus a transformation in God`s power and nature. We have seen the definition of filiation, the origin of a living being from another living being through the communication of substance to similarity with nature. Where you have that, you have the relationship of father and son. None of this is about a period of time between the birth and birth of a son. This passage of time does not result from the nature of filiation, but from the finitude of man, especially from the fact that he does not arise in full possession of all his powers, but must grow slowly. A somewhat old-fashioned, generated adjective is the past section of the verb to generate, which means to conceive or produce as descendants.

You may recognize this word from John 3:16, one of the most popular and quoted Bible verses: “For God has loved the world so much that he has given his only begotten Son, that whoever believes in him should not perish, but have eternal life.” We don`t use words spawned or begotten much in modern English, but everyone still knows what they mean.
