Millersville Christian Academy proclaims as its statement of faith that it adheres to the doctrinal position of Millersville Baptist Church, Inc. of Taylorsville, NC (MBC) found in the Baptist Faith and Message 2000 which states "Baptists cherish and defend religious liberty, and deny the right of any secular or religious authority to impose a confession of faith upon a church or body of churches. We honor the principles of soul competency and the priesthood of believers, affirming together both our liberty in Christ and our accountability to each other under the Word of God.”

Millersville Christian Academy further affirms the North Carolina Christian School Association (NCCSA) Mission Statement as a member school. NCCSA is an educational association established to protect and preserve the freedom of Christian schools in the state of North Carolina; to provide them with quality programs and services; and to aid in the promotion, maintenance, and improvement of their moral, spiritual, and academic standards. MCA will be a continuing member of the North Carolina Christian Schools Association. Membership fees will be paid annually from student registration fees.
