 Bahá 'ís intending to marry are asked to obtain a thorough understanding of the other 's character before deciding to marry . Although parents should not choose partners for their children , once two individuals decide to marry , they must receive the consent of all living biological parents , whether they are Bahá 'í or not . The Bahá 'í marriage ceremony is simple ; the only compulsory part of the wedding is the reading of the wedding vows prescribed by Bahá 'u'lláh which both the groom and the bride read , in the presence of two witnesses . The vows are " We will all , verily , abide by the Will of God . "
