people aren’t happier or less happy in heaven.
Heaven is unity with God. Happiness is an Earthly condition.
Actually, we will only be happy in the truest and fullest sense in heaven. Our earthly condition always involves some mixture of happiness and sorrow or unhappiness.
“Those who are wise shall shine like the brightness of the firmament; and those who turn many to righteousness, like the stars for ever and ever.” (Daniel 12:3)
“There is one glory of the sun, and another glory of the moon, and another glory of the stars; for star differs from star in glory. So is it with the resurrection of the dead…” (1 Cor 15:40-41)
From passages such as these, the parables in the Gospel about the thirty, sixty, and a hundredfold, and many other passages, the Church Fathers conclude that some are happier than others in heaven.
The essential happiness of the saints consists, of course, in their loving union with and vision of God. Even with respect to this happiness some are happier than others in heaven.
The Council of Florence states:
“Illorumque animas, qui post baptisma susceptum nullam omnino peccati maculam incurrerunt, illas etiam, quae post contractam peccati maculam, vel in suis corporibus, vel eisdem exutae corporibus, prout superius dictum est, sunt purgatae, in caelum mox recipi et intueri clare ipsum Deum trinum et unum, sicuti est, pro meritorum tamen diversitate alium alio perfectius.” (Council of Florence–Denzinger, 1305)
“The souls of those who have incurred no stain of sin after having received baptism, and also those which have been cleansed after having contracted the stain of sin, (cleansed either while in their bodies, or after separation from their bodies), are next received into heaven and see clearly the one and triune God as he is. Yet, according to the difference of merits, one sees more perfectly than another.”
A common image used to explain this is different sized glasses. Persons who loved God more on earth are capable of receiving God and seeing God more perfectly in heaven. Yet all persons are filled completely with God, according to their capacity.
Thus all the saints are perfectly happy, yet one is happier than another. Indeed, we could say that all the saints receive infinite happiness (inasmuch as they find their happiness in God, who is infinite goodness), and yet some receive it more than others, and in this sense are happier.
