Right, and when the sell of birds and other sacrificial animals were being sold at the temple, believing they were doing it for a just cause, Jesus turned those tables over and quoted Isaiah.
Matthew 21:12 And Jesus went into the temple of God, and cast out all them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves,
13 And said unto them, It is written, My house shall be called the house of prayer; but ye have made it a den of thieves.
Isa 56:7 Even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices shall be accepted upon mine altar; for mine house shall be called an house of prayer for all people.
Those things that are holy and set apart for the service of God/LORD, such as a church, should not use the same space for pagan traditions. God hates the pagan ways and does not want us to MIX the unholy with the holy.
