A monogram of the name JESUS.
Very truly, I tell you, if
you ask anything of the Father in my name, he will give it to you.
(John 16:23)
Different interpretations of IHS :-
1. It is from the first two letters and
last letter (iota,
eta, and sigma)
of the Greek name of
Jesus, IHSOYS
(most probable)
2. It is from the letters of the Latin name of Jesus, IHESUS
3. Some erroneously say (in the Middle Ages)
that the three letters are the initials of
* "Iesus Hominum
(or Hierosolymae) Salvator"
which means Jesus Saviour of Men, or of Jerusalem=Hierosolyma
* "In
Hoc Signo (vinces)"
which means in this sign (thou shalt conquer),
*
"In Hac Salus"
which means in this (cross) is salvation
