Why is the FISH a symbol of Christianity?

Before I answer this question let me say that I've always wished to swim with dolphins. But I couldn't afford such a holiday so I went swimming with sardines instead.

As soon as they saw me all the sardines swam away leaving me alone in the sea as a subject of ridicule and fun. The chief-sardine said: "Oh it's him again ... let's get away as soon as possible!" and they all left at once!

Now sardines are not as clever as dolphins are they? Why else would they get into a tin and leave the key on the outside?

Every other canned fish you buy, tuna, salmon, pilchard and so on, you have to open with a can opener. But sardines ... they have a key on the outside. Why?

Unless of course you buy those tins with a ring pull. Again, on the outside ... so the sardines can't pull the ring and get out.

Anchovies aren't that much cleverer either. They thought they'd avoid capture by being so salty that no one would ever eat them. They were wrong. They've now become a delicacy much sought after and more fished than before. Who'd ever heard of anchovies on pizza before they became salty?

Come to think of it, most fish are somewhat stupid. They have the whole ocean to swim in and yet they swim into cans and tins and put a label on the outside to make themselves more marketable.

And now about the original question ...

Why is the FISH a symbol of Christianity?

The symbol of a fish was found on ancient Christian monuments and buildings. It represents Christ.

The Greek word for "fish" is ICHTHUS.

If we take the letters of that word they provide the first letters of other Greek words.

Iesous Christos Theou Uios Soter

Jesus Christ, Son of God, Saviour

So the symbol of the fish suggests all this to a Christian. It may well have been a secret sign used by early Christians to identify each other.
