What common beliefs do all followers of Christ have?
I think most followers of Christ believe in what is said in the Apostles Creed. I believe in God, the Father Almighty, the Creator of heaven and earth, and in Jesus Christ, His only Son, our Lord: Who was conceived of the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died, and was buried. He descended into hell. The third day He arose again from the dead. He ascended into heaven and sits at the right hand of God the Father Almighty, whence He shall come to judge the living and the dead. I believe in the Holy Spirit, the holy church, the communion of saints, the forgiveness of sins, the resurrection of the body, and life everlasting.
