A great meditation for this feast from a sermon by Saint Bernard about the feast.
From the Universalis: Office of Readings:
"Why should our praise and glorification, or even the celebration of this feast day mean anything to the saints? What do they care about earthly honours when their heavenly Father honours them by fulfilling the faithful promise of the Son? What does our commendation mean to them? The saints have no need of honour from us; neither does our devotion add the slightest thing to what is theirs. Clearly, if we venerate their memory, it serves us, not them. But I tell you, when I think of them, I feel myself inflamed by a tremendous yearning.
Calling the saints to mind inspires, or rather arouses in us, above all else, a longing to enjoy their company, so desirable in itself. We long to share in the citizenship of heaven, to dwell with the spirits of the blessed, to join the assembly of patriarchs, the ranks of the prophets, the council of apostles, the great host of martyrs, the noble company of confessors and the choir of virgins. In short, we long to be united in happiness with all the saints. But our dispositions change. The Church of all the first followers of Christ awaits us, but we do nothing about it. The saints want us to be with them, and we are indifferent. The souls of the just await us, and we ignore them.
Come, brothers, let us at length spur ourselves on. We must rise again with Christ, we must seek the world which is above and set our mind on the things of heaven. Let us long for those who are longing for us, hasten to those who are waiting for us, and ask those who look for our coming to intercede for us. We should not only want to be with the saints, we should also hope to possess their happiness. While we desire to be in their company, we must also earnestly seek to share in their glory. Do not imagine that there is anything harmful in such an ambition as this; there is no danger in setting our hearts "
