The Holy Family is the exception to the natural model, in which God created the man and woman both the same age of 30, the age of perfection.
Spouses are meant to grow together in God's plan and marriage is a companionate relationship.
The purpose of Marriage is the procreation of children. At the age of 30 women's fertility begins to decrease. Peak fertility is 22 years old. Men instinctively know this. It is a biological reality which is foolish to deny. And yes, the relationship between men and women is all about procreation.
Where I am from which is a Catholic country (not Moslem or Mormon), traditionally, it used to be that a girl was ready for Marriage at age 15. Everyone knew this as a matter of fact. Therefore, their parents threw a "
Quinceanera" party in order to introduce the girl to society and potential suitors. Part of the rite was that the father changed the girls flat shoes for little heels, as a symbol of the girl passing from childhood to womanhood.
I am curious, where did you learn that Adam and Eve were 30 years old? Adam and Eve were created in a state of perfection; but after their epic fall, everything is different. Men and women definitely are, think, and age
very differently.I do not know how old you are but I think when you are 40 years, your perception of things may change.
