Hayes and Jean Minnick firmly believed:
- In the plenary, verbal inspiration of the Holy scriptures, that they are inerrant in the original writings, and that they are of supreme and final authority in faith and life.
- That there is one God existing in three Persons: The Father, the Son, and the Holy Spirit. These three are one God, the same in substance, equal in power and glory.
- In the virgin birth, absolute deity, sinless Life, and atoning death of Jesus Christ as a representative and substitutionary sacrifice, and that all who believe in Him are justified on the ground of His shed blood.
- In the resurrection of the crucified body of our Lord, in His ascension into heaven where He ever Liveth as our High Priest and Advocate.
- In the personal, physical, visible, premillennial return of our Lord and Savior Jesus Christ.
