"The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament"
[Catechism of the Catholic Church CCC 1601]
Marriage is probably the most important decision of your life.
In marriage a man and a woman create between themselves a loving partnership of their whole life. Their lifelong union is based on the free consent and solemn promise of love, which Bride and Groom give to and receive from each other. Their consent is witnessed and blessed by the Church on their Wedding Day.
You should prepare and plan for your Marriage with great care.
