Marriage cannot be contracted except by free and full consent duly expressed by the spouses.
 
a) With due respect for the traditional role of the families in certain cultures in guiding the decision of their children, all pressure which would impede the choice of a specific person as spouse is to be avoided.
 
b) The future spouses have the right to their religious liberty. Therefore to impose as a prior condition for marriage a denial of faith or a profession of faith which is contrary to conscience, constitutes a violation of this right.
 
c) The spouses, in the natural complementarity which exists between man and woman, enjoy the same dignity and equal rights regarding the marriage.
