Who proposed cross as symbols of christians?
The cross was not an accepted symbol in the first few centuries because of the horrific death of Christ on the cross. As early as the second century the marking of a cross upon the forehead and the chest was regarded as a talisman against the powers of demons. A few more murky explanations come with the story that involve an interpretation of the Greek X a celestial sign of God in the third century by Constantine. Also In order to increase the prestige of the apostate ecclesiastical system, pagans were received into the churches a and were permitted to retain their pagan signs and symbols which was the Tau or T, in its most frequent form, with the cross-piece lowered and it was finally adopted to stand for the ‘cross’ of Christ.’ I can’t believe someone would reference Zeitgeist has a reliable source on anything. That thing is so badly produced and loaded with biased, racist, sensationalist, boring, paranoid, common information mixed with misinformation with pseudo-science thrown in.
