The Christian States Congress is the bicameral legislature of the federal government of the Union of Christian States consisting of two houses: the Christian States House of Representatives and the Christian States Senate. Congress meets in the Christian States Capitol in Beaumont, Texas.

Both representatives and senators are chosen through direct election. Congress has a total of 168 voting members: 135 members in the House of Representatives and 28 members in the Senate. Members of the House of Representatives serve two-year terms representing the people of a district. Congressional districts are apportioned to states by population using the Christian States Census results, each state in the union having at least one representative in the House of Representatives. Regardless of population, each of the 14 states has two senators; the 28 senators each serve a six-year term. The terms are staggered so every two years approximately one-third of the Senate is up for election. Each staggered group of one-third of the senators are called 'classes'. No state of the Christian States has two senators from the same class. Most incumbents seek re-election, and their historical likelihood of winning subsequent elections exceeds 90 percent. Senators are limited to two terms, however Representatives may serve three.
