Feb. 9, 2021 Catholic News Service WASHINGTON This year, World Marriage Day, observed annually on the second Sunday of February, will be celebrated Feb. 14, which also is the feast of St. Valentine and which since the eighth century has been a celebration of love and affection. In the United States, National Marriage Week leads up to World Marriage Day and this year s theme for the weeklong observance, which began Feb. 7, is To Have, To Hold, To Honor. The theme was chosen to highlight how married couples live and renew their wedding promises daily in the building up of the domestic church in their homes, particularly as many couples and families have spent more time at home together this year, said a news release from the U.S. Conference of Catholic Bishops.
