This side of the afterlife, we cannot know the status of any two individuals in heaven; in this case, we can only know that both Mother Teresa and the Good Thief are in heaven. What we can know is that those in heaven have attained perfect happiness according to their ability to receive it. As an analogy, when you pour liquid to the rim in a shot glass and in a stein, both glasses are full; but since the stein can hold more liquid than the shot glass, it has a greater capacity to receive more liquid. In the same way, all in heaven will receive all the love they can hold according to their ability to receive it.
