Comforter

the designation of the Holy Ghost (John 14:16, 26; 15:26; 16:7;
R.V. marg., "or Advocate, or Helper; Gr. paracletos"). The same
Greek word thus rendered is translated "Advocate" in 1 John 2:1
as applicable to Christ. It means properly "one who is summoned
to the side of another" to help him in a court of justice by
defending him, "one who is summoned to plead a cause."
"Advocate" is the proper rendering of the word in every case
where it occurs.

It is worthy of notice that although Paul nowhere uses the
word paracletos, he yet presents the idea it embodies when he
speaks of the "intercession" both of Christ and the Spirit (Rom.
8:27, 34).
