The secret of the LORD is with them that fear him
Psalm 25:14
During the days when persecution was fiercest Christians employed secret codes by which which they could identify if someone, they had never met was a genuine believer. One of the most common passwords employed was the Greek word ICHTHUS, meaning fish.
The Christians developed a Gospel message out of ICHTHUS, all of which point to the Saviour of mankind:
Iesus (Jesus) CHrist (Christ) THeou (God) Uios (Son) Sorter (Saviour)
Therefore, when in conversation a Christian would subtly talk about fish; a fellow believer would recognise the code and therefore true fellowship was possible.
For those of us who enjoy freedom, let us be grateful; for those under persecution, who must resort to codes and passwords, let us pray for security and perseverance.
Walking a Roman street, Two strangers meet, And discuss fishing, Now fellowshipping and praying.
