I would think that, before writing a new catechumenate for those wishing to marry and for accompanying people in married life, the pope, bishops, canon lawyers, theologians need to understand married life today, and particularly the role of women in the world and in the family.  "in the world and in the family."  Both.  One of the problems with the traditional view of marriage is that it envisions women as having only the roles of wife/mother (or old maid aunt/celibate nun, but they are not the issue).  Women today work and have career outside the home - finding a way to balance both family life and life outside the home is part of the problem.

They need to be talking to single and married men and women, couples where both are heavily invested in working careers, couples who divorced because they could not find a way through the stresses.  They need to look at how their "view" still treats women as property, stupid, and without a voice or a choice in how their married lives unfold.
