These standards of Bahá'í conduct, which he himself has set forth in his last general epistle, 'The Advent of Divine Justice', and which it should be the paramount duty of every loyal and conscientious believer to endeavour to uphold and promote, deserve serious study and meditation . . .

The principles and methods laid down by the Guardian in his 'The Advent of Divine Justice' on the vital subject of Bahá'í ethics should indeed prove of valuable inspiration and guidance to all the students and friends attending the Summer School classes, and thus prepare them to better appreciate the privileges, and more adequately discharge the responsibilities, of their citizenship in the World Order of Bahá'u'lláh.
