As Ephesians 4:11: "And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, " says, we acknowledge the five fold ministy including apostles and prophets.
As the First Corinthians Chapter 12 says, we believe that the nine gifts of the Spirit (tongues, healings, prophecy, etc.) are still given to the church today; we activate them.
We believe that the church is the body of Christ; when we believe in Jesus Christ to be a child of God, we become part of the universal church made up of true Christians and, at the same time, part of a local church.
We take bread and wine in the Holy Communion as Chrsit's body and His blood, not as just symbols.
We do not celebrate Christmas because it is not recorded in the Bible; the birth of Christ does not agree with Christimas day; Christmas originates in the pagan festival of the Sun and so on. However, for the sake of an evangelism purpose, we reach out to people, using "Christmas."
