John testifies concerning him. He cries out, saying, “This was he of whom I said, ‘He who comes after me has surpassed me because he was before me.’ “ (NIV)
This verse is occasionally used to support the Trinity because it is assumed that for Jesus to come “before” John he would have had to exist before John. While it is true that the Greek word “before” (protos) can mean “before in time,” it can just as easily be “first,” “chief,” “leader,” etc. The “first” and great commandment was not the first given in time, but the first in rank. There are many examples of this in Scripture, including: Matt. 20:27; 22:38; Mark 6:21; 10:44; Luke 11:26. John the Baptist recognized that Jesus was above him in rank, and said so plainly.
