This study examines the relationship between denominational, theological, and organizational indicators and ecumenism between Black and White churches based on a national sample of Black churches across seven denominations and logistic regression modeling. Findings suggest that denominational and organizational indicators are consistently important in explaining ecumenism. Churches associated with the Presbyterian, United Methodist, and African Methodist Episcopal Zion traditions are more likely than Baptists to engage in ecumenism. Furthermore, congregations that: have larger memberships; are located in rural areas; are frequently exposed to sermonic references to racial situations; sponsor youth programs; and, have formally educated pastors are more likely to engage in ecumenical activities.
