Marriage is going to become a word that will be avoided like "gay" and "partnership."
Monsignor Pope makes a proposal:
So the bottom line is that what the secular world means by the word “marriage” is not even close to what the Church means. The secular world excluded every aspect of what the Church means by marriage. Is it time for us to accept this and start using a different word? Perhaps it is, and I would like to propose what I did back in March of 2010, that we return to an older term and hear what you think.I propose that we should exclusively refer to marriage in the Church as “Holy Matrimony.”According to this proposal the word marriage would be set aside and replaced by Holy Matrimony. It should be noticed that the Catechism of the Catholic Church refers to this Sacrament formally as “The Sacrament of Matrimony.”The word “matrimony” also emphasizes two aspects of marriage: procreation and heterosexual complementarity. The word comes from Latin and old French roots. Matri = “mother” and mony, a suffix indicating “action, state, or condition.” Hence Holy Matrimony refers to that that holy Sacrament wherein a woman enters the state that inaugurates an openness to motherhood. Hence the Biblical and Ecclesial definition of Holy Matrimony as heterosexual and procreative is reaffirmed by the term itself. Calling it HOLY Matrimony distinguishes it from secular muddle that has “marriage” for its nomen.
