Here’s an opening litany based on Psalm 15.
(from Psalm 15)
Who may worship in your sanctuary, O Lord?
Who may enter your presence on your holy hill?
Those who obey God in everything
and always do what is right,
who speak the truth from sincere hearts.
Those who do not speak evil about other people,
or wrong their neighbors,
or slander their friends.
Those who loath evil and evil-doers,
but honor those who fear God;
those who keep their promises,
even when it hurts.
Those who do not charge interest on the money they lend
and refuse to accept bribes to do what they know is wrong.
These are the people who will stand firm forever.
