The mission and purpose of this church shall be to fulfill the commission of Christ, given to His apostles, and incumbent on every generation of His church, “to preach the gospel of the Kingdom of God as a witness unto all nations"; to "make disciples of all nations," "teaching them to observe all things whatsoever I have commanded you." This constitutes the primary purpose of the church, and, as such, represents the very justification and requirement for its existence.
Further, the goals of this church shall be:
(1) To convert and baptize believers as God adds to His church through His calling as expressed by Jesus Christ who said, "Come unto me, all ye that labor and are heavy laden and I will give you rest" (Matthew 11:28) and "If any man thirst, let him come unto me, and drink" (John 7:37), and who said to His disciples, "Lift up your eyes and look on the fields, for they are white already to harvest” (John 4:35), and who inspired Luke to write, "And the Lord added to the church daily such as should be saved" (Acts 2:47).
(2) To educate, instruct, encourage, inspire, and edify those added to the church in all the teachings of Jesus Christ.
(3) To conduct radio and or television or other media campaigns to further the message of the church.
(4) To Establish at such time as God provides and His work requires, such educational, cultural, and charitable programs as deemed appropriate to further the stated objectives, goals and purposes of the church and the transaction of any or all lawful business for which the said objectives may be achieved.
A member of the Church of God of Montgomery, Sabbath Day is one who, as defined by Scripture, has repented, has been baptized by immersion (Romans 6), and has received the Holy Spirit (Acts 2:38) as evidenced by the fruits manifest in his life. Such persons are considered no longer “carnally minded” (Romans 8:7), but “in the Spirit”, since the Spirit of God now abides within them through indwelling presence. A "member" Is considered a brother or a sister in Christ; a part of the body of Christ, which is His church, and therefore, a fellow-laborer with all other members in accomplishing the primary mission and purpose of the church. Members are considered as members for life, except as they may voluntarily choose to disassociate themselves from the church at any time.
This church will rely on God to select the members as He will. It is expected that the result of performing all the stated purposes and goals of the church, will be the repentance, baptism, and conversion of those persons whom God wills to call, and who answer the call of Jesus Christ, "Come unto me." Such calling is accomplished through human instruments used in the hands of God for His agents, and through whom the knowledge of Jesus Christ, and His gospel, is conveyed. It is acknowledged by the church that while the ministry of the church and its lay members may be agents, as instruments in the hands of God for such calling, it is actually God Himself, through the power of His Holy Spirit and the mind of Christ who convicts and calls sinners from the world, bringing about repentance, baptism, and the receiving of the Holy Spirit. Therefore, the church believes it is only possible for those actually being "called" of God to be convicted at this time, and believing this, shall not engage in insistent determined proselytizing, or "membership drives" whatever. Christ's call to the people in his time was an invitation expressed in His statement “Come unto me,” but recognizing that most did not, and that "None can come unto the Son except the Spirit of the Father draw him”.
