it is true that Christians are called to be merciful, loving , forgiving , slow to anger but it does not mean we should never judge, we must judge righteously and when someone is turning a house of worship into a den of thieves we should be zealous and show our zeal and go against it.
Jesus Cleanses the Temple
13 Now the Passover of the Jews was at hand, and Jesus went up to Jerusalem. 14 And He found in the temple those who sold oxen and sheep and doves, and the money changers doing business. 15 When He had made a whip of cords, He drove them all out of the temple, with the sheep and the oxen, and poured out the changers’ money and overturned the tables. 16 And He said to those who sold doves, “Take these things away! Do not make My Father’s house a house of merchandise!” 17 Then His disciples remembered that it was written, “Zeal for Your house has eaten Me up.”
18 So the Jews answered and said to Him, “What sign do You show to us, since You do these things?”
19 Jesus answered and said to them, “Destroy this temple, and in three days I will raise it up.”
20 Then the Jews said, “It has taken forty-six years to build this temple, and will You raise it up in three days?”
21 But He was speaking of the temple of His body. 22 Therefore, when He had risen from the dead, His disciples remembered that He had said this to them; and they believed the Scripture and the word which Jesus had said.
