The main gist of the Story of St Christopher as told in Wikipedia..
According to the legendary account of his life Christopher was initially called Reprobus.[4] He was a Canaanite 5 cubits (7.5 feet (2.3 m)) tall and with a fearsome face. While serving the king of Canaan, he took it into his head to go and serve "the greatest king there was". He went to the king who was reputed to be the greatest, but one day he saw the king cross himself at the mention of the devil. On thus learning that the king feared the devil, he departed to look for the devil. He came across a band of marauders, one of whom declared himself to be the devil, so Christopher decided to serve him. But when he saw his new master avoid a wayside cross and found out that the devil feared Christ, he left him and enquired from people where to find Christ. He met a hermit who instructed him in the Christian faith. Christopher asked him how he could serve Christ. When the hermit suggested fasting and prayer, Christopher replied that he was unable to perform that service. The hermit then suggested that because of his size and strength Christopher could serve Christ by assisting people to cross a dangerous river, where they were perishing in the attempt. The hermit promised that this service would be pleasing to Christ.
After Christopher had performed this service for some time, a little child asked him to take him across the river. During the crossing, the river became swollen and the child seemed as heavy as lead, so much that Christopher could scarcely carry him and found himself in great difficulty. When he finally reached the other side, he said to the child: "You have put me in the greatest danger. I do not think the whole world could have been as heavy on my shoulders as you were." The child replied: "You had on your shoulders not only the whole world but Him who made it. I am Christ your king, whom you are serving by this work." The child then vanished.
The personal tenuous link to St Christopher.
After I accidentally converted my mother to Christianity at about the age of 12,( me not my mother )
My mother wanted me baptised, although she had done this anyway at my birth, due to the fact I was born very early due to some trauma or other.. I was never told this, but I did find out through other means eventually.
Anyhow, as a Christening gift, I was given a Silver ST Christopher necklace, the image was coated in an Azul blue colour.
(quick tangent: The first skool I attended was run by a Mrs Priestly and was on top of the hill on Silver Street in Reeth, Swaledale.
she was the worst teacher possible, a deeply religious sort, with a loud sharp voice, and always nasty towards us children, and it turned out that the children were about 1 year behind where they should be when they got to the big school in Richmond.
It also turned out she was not married to the man she lived with in the house that came with the school... talk about a doubly hypocrisy... )
I never liked attending Church, but felt obliged to do so, as I prefered helping out on the farm, rather than waste my time in a cold church listening to a load of irrelevant crap being regurgitated but she was going through hard times, so I felt obliged..
I did learn a few things, and did once witness my mother speak in tongues to her friend..
I was even put in the choir, but luckily for me, my voice broke, and I could not hold a note after that to save my life..
There were many lessons to be learned from those days. Finally at about the age of 14 or 15, she said I no longer had to attend church with her.
So, I was free to help out on the farms, and Ironically, one summer whilst out bailing, when I got home, I realised I had lost the pendant, and there would be no chance of finding it again, as I had covered miles in that day around the fields.
I never had any desire to get it back.
It looked something like this...
I have also since unbaptised myself, twice, once in the water, and I also printed 2 documents to that effect and asked my daughter to sign them as a witness, I did not ask her to agree to what I had written, just witness, and if you knew what I know, it is highly relevant that she acted as witness.
Oh, some images of St Christopher from the same WIKI reference...
In Eastern icons, Saint Christopher is sometimes represented with the head of a dog.
Spare me please !!!
