If you totally fulfill the command to love your neighbor you will feel no bitterness or resentment against him whatever he does. If this is not the case, then the reason why you fight against your brother is clearly because you seek after transitory things and prefer them to the commandment of love….
The self-indulgent person loves wealth because it enables him to live comfortably; the person full of self-esteem loves it because through it he can gain the esteem of others; the person who lacks faith loves it because, fearful of starvation, old age, disease, or exile, he can save it and hoard it. He puts his trust in wealth rather than in God, the Creator who provides for all creation, down to the least of living things.
~St Maximos the Confessor
