1912 - Abdul-Baha in America
At the end of the meeting the Master said:
Although I pay great respect to the feelings of people in order that they may not run away or make the least objection, yet the religious ministers of Washington have denounced us.
Then He said:
The denunciation by the leaders of religion is a proof of the greatness and influence of the Cause because no one pays any attention to something insignificant.
Today various clergymen invited the Master to honor their churches by addressing their congregations. He told them that He was unable to accept because He had limited time but that He would be returning to Washington DC. (Mahmud's Diary)
1932 - A little knowledge is dangerous
It is also very important to hold study classes and go deep in the teachings. A great harm is done by starting to teach without being firmly grounded in the literature. "Little knowledge is dangerous" fully applies to the teaching work. The friends should read the writings and be able to quote from the Tablets when discussing subjects pertaining to the Faith.

1947 - concentrate on perfecting our characters
We must concentrate on perfecting our characters as individual Bahá'ís, and on maturing our still embryonic, and as yet improperly understood, World Order; on spreading the Message, according to the provisions of the Divine Plan; and on building a tightly knit world-wide Bahá'í Community. We are relatively few in numbers, and have such a precious, unique and responsible task to carry out. We must concentrate our full forces upon it.
