'One' in the Bible

Now I ask you, lady, not as though I were writing to you a new commandment, but the one which we have had from the beginning, that we love one another.

Anyone who goes too far and does not abide in the teaching of Christ, does not have God; the one who abides in the teaching, he has both the Father and the Son.

for the one who gives him a greeting participates in his evil deeds.
