I've searched the scriptures, in the Acts thru Revelation period, and find nothing to the effect of "believers" using crosses, either one or two pieces, as symbols of their faith in Christ. This period of "cross lessness" covers at least 35 years. So, it stands to reason that at some point after these years, someone, or something, decided that it would be a good idea to use a "cross" as a symbol of faith in Christ. Why choose an instrument of torture and death to represent their faith in a living and resurrected Christ? Their faith was in the livingword and in the preaching (good news, ramifications)of the cross of Christ. Their faith was in the person of Christ, offering himself for their redemption. Their faith was not in an actual wood "cross" nor in a symbol of a wood "cross", which would have amounted to idolatry. Gee, now let's see, who did have "symbols" galore at that time, and who didn't mind carrying pieces of wood, metal, and stone (in sundry shapes and forms)as "symbols" of their faiths. Could it have been, THE PAGANS? Obviously, at some point after the last book of the bible was written, paganism gradually crept into "the faith", with it's symbols and gods. I find no scripture anywhere, either OT or NT, that condoned the wearing or portraying of "spiritual" trinkets. I personally believe that we (Christians) still have a lot of "pagan" baggage, passed on to us from our forefathers. If we use God's light, his written word, on ourselves first, then we can use it to help others who are trapped in darkness. Thanks for lending an ear.
