"Happy as an Easter". It is a way of saying to describe a very happy person. But, for once, the human way of expressing itself alludes to something that is not only human. Easter is the root of all happiness. At least for the Christian it is so. To make himself clearly understood, Saint Paul affirms in a shocking way that "if Christ has not risen, your faith is futile ... Now, however, Christ has risen from the dead, the first fruits of those who have died." Indeed, he adds a load of ninety by saying "If we have had hope in Christ only for this life, we are to be pitied more than all men ... (and he adds) we eat and drink because tomorrow we will die." It is worth going to reread chapter 15 of the first letter to the Corinthians because Saint Paul says many other things to confirm us in the faith in the resurrection of Christ.
The Christian has reason for joy, or happiness, or good humor, or positive vision (let's say how we want) because he knows that this world is a creature of God. And this is the first reason.
The second reason is even stronger and deeper, and is that Jesus is truly risen from the dead and is the "firstfruits" that is, the tread of our own resurrection. Wedding ring. It is a question of faith. The more we adhere to faith, the happier we will be and we will not be afraid of life or death and not even of the coronavirus.
We know well that we must die and that pain is our companion on the road but Jesus has overcome death and has given meaning to our pain.
Therefore it is not an option to be happy as an Easter. If I am not, it is because of my foolishness and superficiality.
