I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Baptists subscribe to a doctrine that baptism should be performed only for professing believers (believer's baptism, as opposed to infant baptism), and that it must be done by complete immersion (as opposed to affusion or sprinkling). Other tenets of Baptist churches include soul competency (liberty), salvation through faith alone, Scripture alone as the rule of faith and practice, and the autonomy of the local congregation. Baptists recognize two ministerial offices, pastors and deacons. Baptist churches are widely considered to be Protestant churches, though some Baptists disavow this identity."?
A:
Which of the following is not a type of baptism: affusion, liberty or sprinkling?
