1912 - Abdul-Baha in America
8 June 1912 Talk at 309 West Seventy-eighth Street, New York
There were two large public meetings held in two churches. In the morning, at the Unitarian Church, `Abdu'l-Bahá spoke on the reality of divine existence and the meaning of the words of Christ that `the Father is in the Son'. He gave the glad tidings of the Manifestation of the Greatest Name and explained some of the new teachings, concluding with a prayer chanted in Persian. The audience was so transformed that everyone wanted to be near Him, if only for a moment. But it was impossible for all.
The second meeting was held in the evening at the Baptist Temple. As the distinguished pastor had previously announced the visit of `Abdu'l-Bahá and the address He was to deliver, and had also invited dignitaries and statesmen from Washington DC and vicinity, this meeting was of great significance. The Master delivered a detailed address on the methods of natural philosophy and of divine religion and then explained the teachings of the Supreme Pen. His explanations made a great impression, attracting all to His presence, such that everyone expressed humility and sincerity. They appeared to be very happy and honored to be in His presence. The Master's heart was elated with the meetings in Philadelphia and often made mention of them. (Mahmud's Diary)
1948 - Baha'u'llah's system not thought needed to establish Peace
I might add that he does not believe any radiations of thought or healing, from any group, are going to bring peace. Prayer, no doubt, will help the world, but what it needs is to accept Bahá'u'lláh's system so as to build up the World Order on a new foundation, a divine foundation!
