Why a fish?
One of the most significant statements the early Christians used was “Jesus Christ, God’s Son, Savior.”
Because Greek was the universal language then (the New Testament books were written in Greek), Christians often said and wrote, “Jesus Christ, God’s Son, Savior” in Greek.
That phrase, if printed as an acrostic (using the first letter of each word), looks like this:
I = Jesus
CH = Christ (anointed)
TH = God
U = Son
S = Savior
The acrostic forms the word ICHTHUS, which is Greek for fish. If Christians needed to know where to gather for worship, they could look for a fish and perhaps an arrow pointing in the right direction. Persecuted Christians, seeing a fish on the door of a home or business, knew it was a safe place occupied by fellow Christians.
