「宗教的シンボルのファッションとしての着用」は罪ですか？

Christianity's symbol-question is as old as the symbol: the cross, an instrument of execution, became wearable — first secretly (the anchor, the fish), then openly after Constantine, then massively. The tradition's own worry is not the wearing but the hollowing: Matthew 23:5's critique of religious display ('broad phylacteries, long fringes') was aimed at the most symbol-laden people of Jesus' day, and his standard was interiority — the symbol must mean what it says. A cross worn by a believer as identification with the crucified (and as quiet availability — 'I'm someone you can ask about faith') is the tradition's norm and blessing. A cross sold as goth accessory, worn with a fetish costume, or flipped upside down as a statement is using the sacred as raw material — the category the tradition calls profanation, cousin to taking the Lord's name in vain (Exodus 20:7). Between those poles sits the vast fashion middle (the gold cross from grandma, the rosary as pop-star styling), where most pastoral counsel is gentle: wear it if it's true, retire it if it isn't, and let the accessory become a question rather than a costume — the wearer may be the only Bible some elevator ever reads.
