“Another argument in favour of this duty [of family worship] is found in the consideration, that all families have particular mercies to acknowledge, and particular wants to make known. Sickness, or death, or trouble, or affliction of various kinds, may make the case of a family peculiar, and call for such supplication as might not be consistently delayed till the public assembly, or might be improper to be brought there, or some mercy may call for acknowledgment during the recess of public worship, which might demand more notice than closet devotion affords; and hence the importance of a family altar on which such offerings may be laid.” — Jonathan Greenleaf, Thoughts on Prayer: Its Duty: Its Form: Its Subjects: Its Encouragements: Its Blessings (1857), pp. 36-37
