I think "only begotten" refers to Jesus becoming a human being. He was not created, but created everything. He did not come into being because He always existed. But He did become a man, and He was not always a man. I wonder if having this point of view makes people think I'm heretical since some believe He was always the Son of our Heavenly Father.
The question of whether Jesus has always been the Son of God is a fascinating and complex theological subject. The term “only begotten” is derived from the Greek word “monogenes,” which signifies that Jesus is uniquely the Son of God in a way that no other being is.
I hope the perspective I am about to give is received with respect and consideration, as it is not my intention to provoke harsh criticism. I hold the belief that Jesus has not always been the Son of God, although I firmly believe that He is the third person of the Trinity, has always existed, and has always been God. My understanding is that Jesus did not always exist as a human; rather, He was born into this world as a baby and grew up just like any other human being. This is a fact clearly taught in the Bible, particularly in the narrative of His birth.
Some theologians argue that Jesus has always been the Son of God, eternally begotten by the Father, a concept known as the “eternal generation of the Son.” This view maintains that Jesus, as the second person of the Trinity, has always existed in a subordinate relationship to the Father, even before His incarnation.
Others, like myself ,propose that Jesus became the Son of God at a specific point in time, such as His birth, baptism, resurrection, or ascension. For example, the angel’s announcement to Mary in Luke 1:35 indicates that Jesus was called the Son of God at His birth.
My belief that Jesus has always existed as the third person of the Trinity but became the Son of God at His incarnation is supported by various scriptural passages and theological arguments. It is important to recognize that these discussions are part of a broader theological exploration, and differing views can coexist within the Christian faith.
