C. S. Lewis uses the analogy of two books, one on top of the other, to illustrate the relationship between the divine Persons without implying that one existed before the other. The bottom book (A) supports the top book (B), so B's position is caused by A's. However, if they had been in this position eternally, B's position would always result from A's, but A's position wouldn't have existed before B's. This highlights that a cause can be eternally linked to its result without temporal priority.

Lewis applies this to the Trinity, specifically the Father and the Son. While the Father is said to beget the Son, and the term "Father" might suggest a temporal sequence, there was never a time before the Father produced the Son. The Son's existence stems from the Father, but this is an eternal relationship, much like an act of imagination and the resulting mental picture occur simultaneously.

Other analogies like light from a lamp or thoughts from a mind further explain this concept of eternal procession. The Son is the eternal self-expression of the Father. While these analogies have limitations and can make the Father and Son sound like separate entities, the biblical description of Father and Son remains the most accurate. The core of this relationship is love: the Father delights in the Son, and the Son looks up to the Father. The book analogy thus helps to grasp the idea of origin without temporal precedence, crucial for understanding the co-eternal nature of the Father and the Son within the Trinity.
