Matthew 23: 23-28
23 "Woe to you, scribes and Pharisees, hypocrites! For you tithe mint, dill, and cummin, and have neglected the weightier matters of the law: justice and mercy and faith. It is these you ought to have practiced without neglecting the others.
24 You blind guides! You strain out a gnat but swallow a camel!
25 "Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the plate, but inside they are full of greed and self-indulgence.
26 You blind Pharisee! First clean the inside of the cup, so that the outside also may become clean.
27 "Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs, which on the outside look beautiful, but inside they are full of the bones of the dead and of all kinds of filth.
28 So you also on the outside look righteous to others, but inside you are full of hypocrisy and lawlessness.
And then there's that whole book of Amos business.
Don't those Christians read their Bibles? or only the parts they like?
