At each service daily, a prayer, or 'collect' is used from the Book of Common Prayer. The collect for this week the Second Sunday of Lent is:
ALMIGHTY God, who seest that we have no power of ourselves to help ourselves; Keep us both outwardly in our bodies and inwardly in our souls; that we may be defended from all adversities which may happen to the body and from all evil thoughts which may assault and hurt the soul; through Jesus Christ our Lord. Amen.
