Please read the Scripture passage before the homily.
What we believe has consequences. If we believe in all the stuff that Political Party Z puts out, we will vote Z; if we believe that Party A has all the right answers, then we shall vote for candidate A.
Wd believe in the oneness of God and that this God made the whole of creation. We therefore have these consequences. We must be kind, compassionate and forgiving to one another. We must be imitators of God, not of anyone else or anything else.
The author mentions immorality, impurity and greed as things to be avoided. He calls such things idolatry, that is, the worship of strange gods. He sees these behaviors as especially manipulative, self-serving, and selfish, imaginary attempts to replace God with self. He sees that as an attempt to god in the image of self.
To speak of immorality, impurity and greed is not to talk about sexual behavior or the accumulation of money; it is to turn our minds, bodies, hearts and pockets into objects of worship, into tools that elevate us over God and everyone else. The moral, the pure, the un-greedy person has a heart free of constraint, free of deceit, free of selfishness so as to find in God the well-being and purpose of living.
In short, we have to be imitators of God, not make God imitate us.
