We read at Genesis 1:1:
"In the beginning when God created the heavens and the earth.. "
We also read at John 1:1:
"In the beginning was the Word, and the Word was with God, and the Word was God."
It is evident that the phrase "In the beginning"as used by John has a different meaning vis-a-vis the phrase used in Genesis , in that John is refering to a period of time which existed before Creation. But then, we also say that God had no beginning. My question therefore, is: How does the Catholic Church explain the nuances of the term "In the beginning"as used by John the Evangelist and the author of Genesis ?
