Our Apostolic Faith is one which was born out of a Jewish community that believed in One God (Monotheism) and they continued in that same faith.
Ephesians 4:3-7 says
3.Endeavouring to keep the unity of the Spirit in the bond of peace. 4.[There is] one body, and one Spirit, even as ye are called in one hope of your calling; 5.One Lord, one faith, one baptism, 6.One God and Father of all, who [is] above all, and through all, and in you all. 7.But unto every one of us is given grace according to the measure of the gift of Christ.
Live and be a blessing!
