Then Jesus told him, "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed." John 20:29
In fact, the requirement for faith without evidence is often emphasized throughout the New Testament quite often. Hebrews 11:1 defines faith as: Now faith is confidence in what we hope for and assurance about what we do not see. Despite these requirements of faith without evidence Christians seem to lose their minds every time an "archaeological" find is believed to be related to Christianity or is considered by believers to be a holy relic.
The James Ossuary
On October 21,2002 the discovery of the James ossuary was presented to the world. It was considered by the Christians to be a significant find because if proven authentic it would serve as evidence of the existence of an historical Jesus Christ. Inscribed on the side of the box in Aramaic are the words: Ya'akov bar-Yosef akhui diYeshua (English translation: "James, son of Joseph, brother of Jesus"). There is no known direct physical evidence of the existence of an historical Jesus but theists for some reason feel the need to validate their myths. My question is the following: Who are they really trying to convince?
The shroud of Turin
Everyone knows about the famous forgery the shroud of Turin. Many theists cling tenaciously to the belief that this was the actual burial cloth that Jesus body was wrapped in during his entombment! It is relics like these that many theists especially Catholics love to cling to as proofs that what they believe is true. There are enough nails of the so called cross of Christ the world over to build a house with! This is due for the most part that these so called holy relics are actually worth a lot of money and can be sold for a very high price. It has turned Christianity into a very lucrative enterprise and it is because of this that many people have gone out of their way to create very elaborate forgeries in hopes of landing a huge financial reward for their efforts.
The blood of Jesus!
Some churches are claiming to have samples of the blood of Jesus himself! The funny thing about this is that people actually believe it. Catholics seem more prone to believing in holy relics than any other Christian group on the planet. I think that the reason for this is because it has always been a part of their tradition to revere all things they deem to be holy. The church is known to preserve the bodies of people they deemed saints and in the earlier periods of their history they were even known to dismember bodies of saints and send the various body parts to different churches. Some claimed that these holy body parts were responsible for some very incredible miracles.
My question is that if faith should be sufficient to sustain ones beliefs then why this interest in relics to supposedly validate your faith?
And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him. Hebrews 11:6
Anyone who is interested in learning more about holy relics and the ridiculous claims surrounding them should read the following books which I highly recommend on the matter.
