President Tsai Ing-wen (蔡英文) yesterday paid tribute to the Presbyterian Church’s contributions to the nation at an event marking the 150th anniversary of the appointment of one of the church’s first missionaries in Taiwan. Tsai delivered the remarks at a prayer service held by the Presbyterian Church of Taiwan in honor of George Leslie Mackay, a Canadian minister who spent three decades in Taiwan from late 1871 until his death in 1901. In addition to establishing more than 60 churches in Taiwan, Mackay is widely remembered as the founder of Aletheia University, originally called Oxford College, in New Taipei City’s Tamsui District
