It is legitimate aspiration to constitute a family which does not in any way imply attachment and neither is marriage or parenthood an earthly thing in the trivializing temporal sense you frame it.
on the contrary, marriage is a good of the earth, Jesus said it clearly, on the other side it does not exist anymore. If not on the other side, the married should continue their conjugal life, which is absurd.
To the contrary, the orthodox would be the first to say that marriage is a reflection of divine nature the union between the spouses reflecting the union between the persons of the Holy Trinity. And as for aspiring to the gift of life I’d hardly call it earthly instead heavenly.
it is all nature that is a reflection of God, Jesus himself has chosen the image of the vine and branches as an image of the union he has with Christians. This does not confer on the vineyard, a dignity of Heaven.
Jesus also chose the image of a polygamous husband to show the union that exists between him and the souls, it does not give a value to the polygamous marriage.
So the fact that marriage is an image of the holy trinity does not confer on it any spiritual excellence.
Even the saints showed impatience and hurt at times when their vocation and state of life met impediments.
they were religious vocations. Marriage is not a religious vocation, it is a natural vocation.
So I will say things clearly. To make his message interesting in a world that has become too sensual, the current pastoral care of the Church has chosen to overestimate marriage and couple life in general, by making believe that natural happiness can be ordered to spiritual happiness. In short, we subtly try to say that there is a Christian hedonism alongside the traditional Christian dolorism
