Broad list of ‘Abdu’l-Baha’s accomplishments – summarized by the Guardian

Through Him the Covenant, that “excellent and priceless Heritage” bequeathed by the Author of the Bahá’í Revelation, had been proclaimed, championed and vindicated.

• Through the power which that Divine Instrument had conferred upon Him the light of God’s infant Faith had penetrated the West, had diffused itself as far as the Islands of the Pacific, and illumined the fringes of the Australian continent.
• Through His personal intervention the Message, Whose Bearer had tasted the bitterness of a life-long captivity, had been noised abroad, and its character and purpose disclosed, for the first time in its history, before enthusiastic and representative audiences in the chief cities of Europe and of the North American continent.
• Through His unrelaxing vigilance the holy remains of the Báb, brought forth at long last from their fifty-year concealment, had been safely transported to the Holy Land and permanently and befittingly enshrined in the very spot which Bahá’u’lláh Himself had designated for them and had blessed with His presence.
• Through His bold initiative the first Mashriqu’l-Adhkár of the Bahá’í world had been reared in Central Asia, in Russian Turkistán, whilst through His unfailing encouragement a similar enterprise, of still vaster proportions, had been undertaken, and its land dedicated by Himself in the heart of the North American continent.
• Through the sustaining grace overshadowing Him since the inception of His ministry His royal adversary had been humbled to the dust, the arch-breaker of His Father’s Covenant had been utterly routed, and the danger which, ever since Bahá’u’lláh had been banished to Turkish soil, had been threatening the heart of the Faith, definitely removed.
• In pursuance of His instructions, and in conformity with the principles enunciated and the laws ordained by His Father, the rudimentary institutions, heralding the formal inauguration of the Administrative Order to be founded after His passing, had taken shape and been established.
• Through His unremitting labors, as reflected in the treatises He composed, the thousands of Tablets He revealed, the discourses He delivered, the prayers, poems and commentaries He left to posterity, mostly in Persian, some in Arabic and a few in Turkish, the laws and principles, constituting the warp and woof of His Father’s Revelation, had been elucidated, its fundamentals restated and interpreted, its tenets given detailed application and the validity and indispensability of its verities fully and publicly demonstrated.
• Through the warnings He sounded, an unheeding humanity, steeped in materialism and forgetful of its God, had been apprized of the perils threatening to disrupt its ordered life, and made, in consequence of its persistent perversity, to sustain the initial shocks of that world upheaval which continues, until the present day, to rock the foundations of human society.
• And lastly, through the mandate He had issued to a valiant community, the concerted achievements of whose members had shed so great a lustre on the annals of His own ministry, He had set in motion a Plan which, soon after its formal inauguration, achieved the opening of the Australian continent, which, in a later period, was to be instrumental in winning over the heart of a royal convert to His Father’s Cause, and which, today, through the irresistible unfoldment of its potentialities, is so marvellously quickening the spiritual life of all the Republics of Latin America as to constitute a befitting conclusion to the records of an entire century.
