No one is adding two persons or three persons for that matter. Who is teaching you this stuff, tell me what church do you attend that would come up with these ridiculous conclusions? Look, John 1:1 says, "In the beginning was the Word/Logos, and the Word/Logos was WITH God, and the Word/Logos was God."
Vs2, He or the Greek literally says, "This one" was in the beginning with God." In other words, Jesus Christ was with God and is God. Use some common sense and think! If your with someone you can't be that someone. If your with your father and mother you are not them, you are your own person just like they are their own persons. When the Bible teaches that God is one it's teaching that God is one in nature, not in person.
This is why the Bible clearly identifies God as three distinct persons. This is also why the Jews accused Jesus of blasphemy and wanting to stone/kill Him on numerous occasions especially when He literally said at John 10:30, "I and the Father, WE ARE ONE." Again, one in nature, not in person. This is not hard to understand if you would study your Bible.
Secondly, Jesus was "NOT" begotten in the sense of biological reproduction or physical birth. It does not refer to the conception of Jesus in Mary's womb. Jesus Christ was "sent" from heaven and not made or created by God His Father. John 3:17, "For God did not SEND the Son into the world to judge the world, but that the world should be saved through Him." Or John 3"13. "And no one has ascended into heaven, BUT HE WHO DESCENDED FROM HEAVEN, even the Son of Man."
John 3:34, For He whom GOD SENT speaks the words of God etc. John 5:30, "I do not seek My own will, but the will of HIM WHO SENT ME." John 6:38, "FOR I HAVE COME DOWN FROM HEAVEN, not to do My own will, but the will of the Father WHO SENT ME." John 8:23, "Youo are from below, I am from above, you are of this wiorld, I am not of this world."
Then there is ole Galatians 4:4, "But when the fulness of the time came, GOD SENT FORTH HIS SON, born of a woman, unded the Law. Vs5, in order that He might redeem those who were under the Law, that we might receive THE ADOPTION OF SONS." We are adopted by God, Jesus Christ was not or is not an adopted Son of God.
And notice Isaiah 9:6, "For a child will be born to us, A SON WILL BE GIVEN;" To be given you have to have already existed. If I give you a loaf of bread, the bread all ready exists. And btw, to those who believe that Jesus Christ is God the Father from where Isaiah 9:6 says, "Eternal Father" it is referring to the Son being the "Source of eternity" and not Him being God the Father.
IN GOD THE SON,
