Hopkins is a constructive theologian focusing on contemporary models of theology, black theology, and liberation theologies. He defines black theology as "how God, or the spirit of freedom, works with the oppressed black community for their full humanity." According to Hopkins black theology started with a full-page ad in the New York Times in 1966 by a few black pastors asking for a "theological interpretation of black power." Today it focuses on the area of asking how to include black churches and how to serve them in a crisis. He began working with black theology when a colleague gave him a two-page article about it by James Hal Cone from the Union Theological Seminary in the City of New York. After meeting with the dean at the seminary to discuss points in the article he was enrolled in their master's program and Cone was his new advisor. Hopkins has commented on, and mentioned as a source of inspiration for black liberation theology by Jeremiah Wright. Wright was lead pastor at the church attended by presidential candidate Barack Obama, and the source of some recent controversy. Hopkins attends and has spoken in defence of the Trinity United Church of Christ, often supporting Wright. Hopkins explains Wright's use of "God damn America" was taken out of context as it was theological wordplay, using the word "damn" straight out its specific meaning in the original Hebrew.
"It means a sacred condemnation by God to a wayward nation who has strayed from issues of justice, strayed from issues of peace, strayed from issues of reconciliation…"
Hopkins also stated that attacks on Wright are actually attacks on the very institution of the Black church
"To caricature and attack Jeremiah A. Wright Jr. is to attack the Black church in America…. Attempts to muzzle him and Trinity United Church of Christ in Chicago exemplify a bad omen for every African American preacher and every African American church in the country. And with the Black church censored, other Christian churches will be the next in line.
