I really appreciated this quote, because it speaks volumes about the wrong assumptions people often make when criticizing “Christianity.”  For what they are criticizing is not behavior that Christ taught, but behavior that is often the opposite of what Christ taught.  In addition, the “good” things about secularism nearly always overlap with Christian principles.   

Secularism looks best when secularists live like Christians ought to, but in a way that is inconsistent with their secularism, and Christianity looks worst when so-called Christians live consistent with secularist principles.
