21 so that they may all be ONE, just as you, Father, are IN UNION with me and I am IN UNION with you, that they also may be IN UNION with us, so that the world may believe that you sent me.
22 I have given them the glory that you have given me, in order that they may be ONE just as we are ONE.
23 I IN UNION with them and you IN UNION with me, in order that they may be perfected into ONE, so that the world may know that you sent me and that you loved them just as you loved me.
24 Father, I want those whom you have given me to be with me where I am, in order that they may look upon my glory that you have given me, because you loved me before the founding of the world.
25 Righteous Father, the world has, indeed, not come to know you, but I know you, and these have come to know that you sent me.
26 I have made your name known to them and will make it known, so that the love with which you loved me may be in them and I IN UNION with them.”

The masculine-singular form, "heis" would have to be used if indicating that Jesus and his Father were "one person" .
