Of course, true Christians in the first century never had baptismal questions nor were they required to appear before a service committee, individual elders or any type of ecclesiastical body to prove their faith. Such 'dogma' and requirements were only added later as individual religious denominations needed to make sure that their converted adherents were fully indoctrinated into their belief system and thereby 'qualified' for baptism. All Christian religious systems baptize you into their own particular 'brand'.
"Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus. And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized? And Philip said, If thou believest with all thine heart thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him." - Acts 8:35-38 KJV
