From the USCCB:
The observances of National Marriage Week (Feb. 7-14) and World Marriage Day (Sunday, Feb. 12) are an opportunity to focus on building a culture of life and love that begins with supporting and promoting marriage and the family. This year’s theme, “Marriage…one flesh, given and received” highlights the one-flesh union of husband and wife that is willed by God. It also indicates the personal self-gift of each spouse, one to the other. These concepts point to Christ who gives Himself under the appearance of bread and wine—as real flesh and blood.
The Secretariat on Laity, Marriage, Family Life and Youth offers the following resources to bishops, priests, deacons, married couples, and lay men and women to help celebrate and live the great gift of married life.
