We call that basic philosophy. Blessed are they that have not seen, and have believed (John 20:29)
It is mystical Voodoo alchemy. If you believe it's Gold, then it becomes gold even though it's still (by all appearances) lead. Hey, can I sell you a box of lead colored gold bricks? Only $200 an ounce.
I'm confused by why you think your position is "philosophical." Are you saying tht "philosophically" the bread is the physical body of Christ, but in reality it is bread?
