Rejoice always, pray without ceasing, in everything give thanks; for this is the will of God in Christ Jesus for you.

– 1 Thessalonians 5:16-18


OCF Day of Prayer is a program that unites the various chapters across North America in prayer. Each year, on the first day of Great Lent (Clean Monday), participating OCF chapters take part in 24 hours of unceasing prayer. Each school takes a one-hour slot to pray for themselves, their chapters and their fellow students.
