3. All the moral teaching of Christ resumes itself in the need for charity and humility, that is to say, in the two virtues which are contrary to selfishness and pride. In all of His teaching Jesus indicates these two virtues as being the ones which lead to eternal happiness. He said that the poor in spirit, that is to say the humble, were blessed because the Kingdom of Heaven would be theirs: Blessed are those who have pure hearts; Blessed are the gentle and the peacemakers; Blessed are the merciful. He also taught the need to love one's neighbour as oneself, to do unto others as we would have them do unto us, to love our enemies, to forgive all offences if we wish to receive forgiveness, to do good without ostentation and to judge ourselves before we judge others. So then charity and humility are the two things which Jesus never ceased to recommend and for which He stands as an example. He also never ceased to combat pride and selfishness. Nor did He limit Himself to the mere recommending of charity, but put it in very clear and explicit terms as being the only condition for future happiness.
With respect to the description given by Jesus of the Final Judgement, we must separate, as in many other cases, that which is only form or allegory. The people to whom Jesus spoke, being still unable to understand totally spiritual questions, made it necessary for Him to offer them material images which would both shock and impress. Therefore in order for them to better understand what was being said to them, Jesus was obliged to keep closely to the form of the ideas of those times, always reserving for the future the real interpretation of His words and the points which at that time were unable to be clearly explained. But alongside the accessory or figurative parts of this explanation, there is one dominant feature: that of the happiness reserved for the just and the unhappiness awaiting those who are evil.
What then are the considerations of sentence according to that supreme judgement? On what has the indictment been based? Does the judge perhaps ask if the person under interrogation has fulfilled this or that formality, if they have more or less observed this or that external practice? No, he will ask but one question: if charity has been practised; and then make the pronouncement: "Go to the right all who have helped their brothers and sisters. Go to the left all those who have been unyielding." Is it said, by any chance, what is the orthodoxy of their faith? Is any distinction made between those who believe in this or that manner? No, because Jesus places the Samaritan, considered by some to be a heretic, who practised love towards his fellow creature above any orthodoxy which lacks charity. So do not consider charity to be merely one of the conditions for salvation. But instead, consider it to be the only condition. If there were others to be met, then Jesus would have mentioned them. Since He put charity in first place, it is because it implicitly embraces all the other virtues such as humility, kindness, benevolence, indulgence, justice, etc., and also because it is the absolute negation of pride and selfishness.
