Where is that in the Bible? The closest thing I can think of is Jesus' command to not pray like those hypocrites who go out just to be seen; in other words, out of pride.
Try 2 Cor 6:16-18
Also, from McClintock & Strong’s Encyclopedia of the Bible:
“...in the New Testament idolatry came to mean, not only the giving to any creature or human creation the honor or devotion which belonged to God alone, but the giving to any human desire a precedence over God’s will (1 Cor 10:14; Gal 5:20; Col 3:5; 1 Peter 4:3).”
All I am saying is that we are not required to wear, or carry, or display any particular symbol symbol or item to be considered a Christian; nor, by being forbidden to do so, do we lose our Christianity or Salvation.
When one makes a fetish of having to do so, then it raises that created object to a status of necessity, and it becomes a fetish object, or (so to speak) an amulet or magical talisman; a de facto object of worship or veneration, which is a form of idolatry.
The difference with the Sikhs or Muslims is that they literally believe that being deprived of their items deprives them of their hope of salvation, and that to take them away is literally condemning them to their version of Hell.
Where these things, wrong as they are, are enable... (That should have been 'enabled')
I meant the forbidding by school or other officials of wearing of Christian symbols; that the officials get away with so forbidding because Christians can not honestly claim that, as an essential article of faith, that they must wear the Cross or the ring, etc.
For us, it is optional to wear such items, so the officials feel that it is legitimate to ban them, but wrong to ban what other religions consider essential.
