So the Advocate was going to teach and remind one of all Jesus said. Who does Jesus repeatedly contribute the words he was speaking to = The Only True God and Father. (John 14:10 just one of many examples).
John 3:34 For he whom God hath sent speaketh the words of God: for (because) God giveth not the Spirit by measureunto him. Luke 4:18 - The Spirit of the LORD is on Me, because He has anointed Me to preach good news to the poor. He has sent Me to proclaim liberty to the captives and recovery of sight to the blind, to release the oppressed,
how God anointed Jesus of Nazareth with the Holy Spirit and with power, and how Jesus went around doing good and healing all who were oppressed by the devil, because God was with Him.
Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did through him in the midst of you, as ye yourselves also know: ------------------ Who was the advocate when Jesus was here = Jesus, "So Jesus is not a person either?"
What mental turn come upon you, to come up with that conclusion, from my words ? ----------------------- It would appear you may need to LOOK up what an Advocate means?
"Jesus is the Son of God -> God the Father likeis the advocate, the Holy Spirit?" -> (That was to come back, sparingly it would seem, it turned out, as the Key truths were stolen around 100 - 200 - AD by the CC's and follow to this day).
