"Abdu’l-Baha and the Guardian ‘share . . . the right and obligation to interpret the Bahá'í Teachings’”

The system of Bahá'í Administration is "indissolubly bound with the essential verities of the Faith" as set forth in the writings of Bahá'u'lláh and Abdul'-Baha. A unique feature of this system is the appointment of authorized interpreters, in the persons of Abdu'l-Baha and the Guardian, to provide authoritative statements on the intent of Bahá'u'lláh's revelation. Writing in The Dispensation of Bahá'u'lláh, Shogi Effendi stated that "Abdu’l-Baha and the Guardian " share . . . the right and obligation to interpret the Bahá'í Teachings". In relation to his own function as interpreter, he further stated that "the Guardian has been specifically endowed with such power as he may need to reveal the purport and disclose the implications of the utterances of Bahá'u'lláh and of Abdu'l-Baha". The significance of this important provision is that the religion of God is safeguarded and protected against schism and its essential unity is preserved.

Three kinds of persecution ‘Abdu’l-Baha had to bear

All who stand up in the Cause of God will be persecuted and misunderstood. It has always been so; it will always be so. Let neither enemy nor friend disturb your peace, destroy your happiness, prevent your accomplishment. Fix your soul upon God. Then persecution and slander will make you the more radiant. The purposes of your enemies will be reflected upon themselves. They will be injured instead of you. Oppression is the wind which fans the fire of the love of God. Welcome persecution and bitterness. A soldier may bear arms, but until he has faced the enemy in battle he has no right to a place in the king's army. Let nothing defeat you. God is your helper. God is invincible. Be firm in the Heavenly Covenant. Pray for strength. It will be given you, no matter how difficult the conditions.

When ‘Abdu’l-Baha was sent to Akka, he experienced three kinds of persecution. Two kinds were easy to bear. When he arrived in Akka they placed chains upon his limbs and circlets of steel were locked around his ankles and knees. While the guards were doing this ‘Abdu’l-Baha laughed and sang. They were astonished and said, "How is this? You are laughing and singing. When prisoners are ironed in this way, they usually cry out, weep and lament." ‘Abdu’l-Baha replied, "I rejoice because you are doing me a great kindness; you are making me very happy. For a long time I have wished to know the feelings of a prisoner in irons, to experience what other men have been subjected to. I have heard of this; now you have taught me what it is. You have given me this opportunity. Therefore I sing and am very happy. I am very thankful to you."

After a time the men who had been appointed to keep guard over me became as loving brothers and companions. They strove to lighten my imprisonment by acts of kindness. They said, "In order that you may not be subjected to the jeers of the people when you walk upon the streets we will arrange your clothing so these chains are not visible." They took the chains which were upon my limbs, gathered the ends together and wrapped them as a girdle around my waist, then arranged my clothing so no chains were visible.
