This book comprises essays honoring the life and work of Yiu Sing Lucas Chan, S.J., who died unexpectedly on May 19, 2015, at the end of his first year as a member of the faculty in the Department of Theology at Marquette University. The editors intend to commemorate Chan’s brief but productive career by furthering the critical conversations he started. The essays included thus touch on aspects of the brilliant young Jesuit’s wide-ranging work in the fields of scriptural research, moral theology, and systematic theology. Each essay either engages Chan’s scholarship directly or seeks to advance his design to bridge the disciplinary gaps between scriptural research and constructive theology. This book includes contributions by noted Roman Catholic theologians James F. Keenan, S.J., Bryan N. Massingale, and John R. Donohue, S.J., as well as two original poems by his Marquette colleagues dedicated to Lucas.
