522. First, though, let me state what divine mercy is. Divine mercy is a pure mercy toward the whole human race with the intent of saving it, and it is constant toward every individual, never withdrawing from anyone. This means that everyone who can be saved is saved. However, no one can be saved except by divine means, the means revealed by the Lord in the Word. Divine means are what we refer to as divine truths. They teach how we are to live in order to be saved. The Lord uses them to lead us to heaven and to instill heaven's life into us. The Lord does this for everyone; but he cannot instill heaven's life into anyone who does not refrain from evil, since evil bars the way. So to the extent that we do refrain from evil, the Lord in his divine mercy leads us by divine means, from infancy to the end of life in the world and thereafter to eternity. This is the divine mercy that I mean. We can therefore see that the Lord's mercy is pure mercy, but not unmediated: that is, it does not save people whenever it feels like it, no matter how they have lived.

6706. The different kinds of neighbour - which a member of the Church ought to be thoroughly acquainted with if he is to know the true nature of charity - are determined by the good present in each individual. And since all good comes from the Lord, the Lord is in the highest sense and a supereminent degree the Neighbour and origin of the neighbour. From this it follows that a person is the neighbour in the measure Lord resides with him, since nobody receives the Lord, that is, the good which comes from Him, in the same way as another, no one person is therefore the neighbour in the same way as another. For all without exception in heaven and all without exception on earth differ from one another in good. Good is never exactly one and the same with any two people; variation is essential, in order that each kind of good may continue to exist by itself. But no one, not even an angel, can know all those variations, thus all the distinctions of the neighbour that are determined by the way the Lord is received, that is, the good coming from Him. One can know them in only an overall way, that is, know the general kinds of variation and some of the specific kinds of these. Nor does the Lord demand anything more of a member of the Church than that he should lead a life in keeping with what he knows.
