"…we encourage everyone across this country to STAND together for marriage."
A special day of prayer has been designated by the Stand for Marriage group, as Stand for Marriage Sunday, which is coming up on September 21st.
It is described as a national prayer day that brings together people of faith to "remember, repent and reclaim the institution of marriage."
A statement on the official website says, "In Scripture, we are often called to remember the faithfulness of God, His purposes and His precepts. One of His precious and enduring gifts to us—marriage—is under assault from those who seek to redefine it."
Those wishing to participate in Stand for Marriage Sunday are encouraged to contact their local congregation, or visit the website at the link provided, for more information.
