In 1987 Leonard and Ping-Lan Richardson’s month-long vacation to visit her relatives in Taiwan led to her family’s salvation and the founding of a village church. In 1990 he resigned his pastorate in Bethany, Missouri, and returned with his family to Taiwan as associates in missions. As an AIMer in Taiwan, Richardson started and pastored two churches, taught home Bible studies, reached out to surrounding villages by starting Sunday schools, and helped missionary Tom Bracken whenever possible.
The Richardsons received their appointment as UPCI missionaries to Taiwan in September 1994. He pastors in Nantz, started a work in Tainan, and is involved in prison ministry. He stated, “We make it a point to help the saints to mature in the Spirit. I do not stress evangelism but spiritual growth. It is the laws of nature for the mature to produce after its kind.”
