They say
John 18:20 — Jesus said nothing in secret. Your temple is a cult.
John 18:20 is Jesus before Annas about His public teaching — not a ban on sacred space. He explained parables only to the Twelve. Matthew 7:6: do not give what is holy to dogs. Exodus 28: holy clothing for the priest. Israel already had a Holy of Holies. Early Christians also kept some sacred rites private.
Matthew 7:6
KJV · Give not that which is holy unto the dogs, neither cast ye your pearls before swine.
NRSVUE · Do not give what is holy to dogs; and do not throw your pearls before swine.
Exodus 28:2, 42
KJV · Thou shalt make holy garments for Aaron thy brother for glory and for beauty. … linen breeches to cover their nakedness.
NRSVUE · You shall make sacred vestments for Aaron your brother, for glory and for beauty. … linen undergarments to cover their naked flesh.
