Either you haven't bothered to examine the 230 NT occurrences of the Greek word translated "greater" in John 14:28 or you just don't care what those passages say.
Where did you get the "230" figure?
The word is translated in a variety of ways, and in most cases refers simply to sheer superiority and has nothing at all to do with position or rank.
Ltes look at some examples of where persons are compared to each other (I believe all the following use meizon, however I will later confirm it):
- "Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: . . . " Matthew 11:11
comment: "greater" here certainly does not seem to refer to nature, but to position, authority, godliness, etc.
- " . . . notwithstanding he that is least in the kingdom of heaven is greater than he." Matthew 11:11
comment: this verse is comparing those of the new birth to those of the old birth (compare Colossians 1:13 ) both have the same nature. John the baptist was just as human as Paul (who wrote Colossians). "greater" here does not seem to refer to nature.
- "The men of Nineveh shall rise in judgment with this generation, and shall condemn it: because they repented at the preaching of Jonas; and, behold, a greater than Jonas is here." Matthew 12:41
comment: both Jesus and Jonah had the same human nature. Though Trinitarians believe that Jesus also had a divine nature which was superior by nature to Jonah, I don't specifically recall seeing an appeal to this verse by them for evidence of Jesus' higher nature. Unitarians who believe that Jesus only had a human nature would have to admit that according to their doctrine Jesus and Jonah had the same nature, so accoring to unitarain doctrine "greater" here does not refer to nature.
- "The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here." Matthew 12:42
comment: see above comments; Unitarian doctrine does not teach that greater here refers to nature. They admit that Jesus and solomon were both equally human.
- "And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven." Matthew 18:3-4
comment: He that is humble now is greatest in the kingdom. similar to the concept of he that is humble will be exalted. Probably refers to position rather than nature.
- "But he that is greatest among you shall be your servant. And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted." Matthew 23:11-12
comment: postion most likely in view, not nature.
- "But they held their peace: for by the way they had disputed among themselves, who should be the greatest. And he sat down, and called the twelve, and saith unto them, If any man desire to be first, the same shall be last of all, and servant of all." Mark 9:34-35
comment: clearly seems to refer to position and not nature.
- "For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist: . . . " Luke 7:28
comment: see Matthew 11 comments. "greater" here does not seem to refer to nature.
- " . . . but he that is least in the kingdom of God is greater than he." Luke 7:28
comment: see Matthew 11 comments. "greater" here probably does not refer to nature
- "Then there arose a reasoning among them, which of them should be greatest. And Jesus, perceiving the thought of their heart, took a child, and set him by him, And said unto them, Whosoever shall receive this child in my name receiveth me: and whosoever shall receive me receiveth him that sent me: for he that is least among you all, the same shall be great." Luke 9:46-48
comment: see Mark 9. nature does not seem to be in view
- "The queen of the south shall rise up in the judgment with the men of this generation, and condemn them: for she came from the utmost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here." Luke 11:31
comment: see above under Matthew: According to Unitarain doctrine "greater" here does not refer to nature. Trinitarians doctrine does not require greater here to refer to nature.
- "The men of Nineve shall rise up in the judgment with this generation, and shall condemn it: for they repented at the preaching of Jonas; and, behold, a greater than Jonas is here." Luke 11:32
comment: see above
- "And there was also a strife among them, which of them should be accounted the greatest." Luke 22:24
comment: the disciples were clearly seeming to be fighting over position, not nature
- "But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve." Luke 22:26
comment: "greatest" here clearly does not seem to refer to nature, but position, authority, etc.
- "For whether is greater, he that sitteth at meat, or he that serveth? is not he that sitteth at meat? but I am among you as he that serveth." Luke 22:27
comment: "greater" here clearly does not seem to refer to nature, but position, etc.
- "The woman saith unto him, Sir, thou hast nothing to draw with, and the well is deep: from whence then hast thou that living water? Art thou greater than our father Jacob, which gave us the well, and drank thereof himself, and his children, and his cattle?" John 4:11-12
comment: I think that is if far more likely that the woman was refering to human greatness rather than a comaparison of essential nature.
- "Art thou greater than our father Abraham, which is dead? and the prophets are dead: whom makest thou thyself?" John 8:53
comment: I think that it is more likely that the religious leaders were refering to human greatness (such as position above other prophets) rather than to a comparison of essential natures.
- "Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him." John 13:16
comment: "greater" here clearly seems to refer to postition and not nature.
- "Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also." Matthew 15:20
comment: see above under John 13:16 Jesus quoted his illustration in John 13:16 where greater clearly seems to refer to position, not nature.
- "But there was a certain man, called Simon, which beforetime in the same city used sorcery, and bewitched the people of Samaria, giving out that himself was some great one: To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God." Acts 8:9-10
comment: greatest does not seem to refer to nature
- "Whereas angels, which are greater in power and might, bring not railing accusation against them before the Lord." 2 Peter 2:11
comment: "greater" here is defined in the text as refering to "power and might." Though angels and humans have a different nature, the term "greater" here only demonstrates that man has less power and might than angels, a function of different quantity, not necessarily quality.
