Andrew and Terri Lyke are retired ministry consultants and pioneers in Catholic marriage ministry. The mission of their ministry has been to strengthen the institution of marriage in the African-American community. The focus of that work has been in marriage education, spiritual formation, and ongoing social support through outreach from faith-based communities. 

Facilitating retreats, workshops, relationship coaching, and parish consultations, their mission has been to raise our sights on how we, the body of Christ, live in the Light of God's grace through the Sacrament of Holy Matrimony. Highlighting the symbiotic relationship between the couple and the community, they promote an "African worldview," recognizing the "I" in the "We" for the mutual support between marriage and community. Their book, Marriage On A Lampstand: Exploring a New Paradigm for Modern Christian Marriage (Heavenly Light Press), offers foundations and a blueprint for marriage faith formation for couples and their faith communities.

The Lykes were married in 1975 and began their life in marriage ministry in 1981 when they, with other couples and priests began Marriage Ministry for the Black Community in the Archdiocese of Chicago. They designed the Arusi Retreat in 1994 and have presented the weekend program in dioceses across the United States and in the Caribbean. They served as advisors to the USCCB committee on Marriage and Family. From 1999 to 2009, Andrew served the Archdiocese of Chicago as the Coordinator of Marriage Ministry. In that role he was the principal writer of In The Spirit of Cana—Guidelines for Pastoral Outreach to Christian Marriage: Formation, Preparation, Celebration, and Continuing Education. In 2011, he was rehired as the Director of the Office for Black Catholics, a role in which he served until 2015.

In 2016, they hosted the National Black Catholic Marriage & Family Symposium in Chicago. Since retiring from full-time ministry, they have done infrequent virtual webinars and collaborations on various ministry projects related to marriage and family life, Catholic anti-racist activism, and Black Catholic empowerment. "Mom and Dad" to two adults, they are "Nana and Papa" to six grand-blessings.
