Although the Japanese government prohibited the teaching of the Bible in government schools, Clark managed, after considerable effort, to secure approval from Kuroda to make use of the Bible during ethics instruction. In doing so, Clark introduced Christian principles to the first entering class of the college. They, in turn, influenced the students in the second class who enrolled after Clark's departure. In 1877, 31 students of SAC converted to Christianity, signing a document drafted by Clark titled, "The Covenant of Believers in Jesus." Some of them later played important roles in the fields of Christianity, education, and international relations during Japan's continuing modernization in the early 20th century. Alumni such as Uchimura Kanzō (founder of the non-church movement, a Japanese Christian society) and Nitobe Inazō (Quaker, educator and diplomat), still known nationwide in Japan, were from the second entering class of the College.
