Seven as a Religious Symbol

The 7th letter of the Armenian alphabet is է (Pronounced 'Eh')

է = էութիւն = Eyoutioun = Etre = Being

The Armenian capital letter է pronounced "Eh",
the seventh letter of the alphabet,
when used in a sentence in a religious context,
is a direct reference to God and means, "He exists".
The letter often appears at the top of encyclicals and letters issued by

the Catholicos to mean "God", "of God",
and "in the name of God", and is based on the book of Exodus 3: 1-14.

In every Armenian Apostolic Church we see this letter carved in stone and put high above the altar
