One who believes; one who is persuaded of the truth or reality of some doctrine, person, or thing.
One who gives credit to the truth of the Scriptures, as a revelation from God; a Christian; -- in a more restricted sense, one who receives Christ as his Savior, and accepts the way of salvation unfolded in the gospel.
One who was admitted to all the rights of divine worship and instructed in all the mysteries of the Christian religion, in distinction from a catechumen, or one yet under instruction.
I'm a great believer that any tool that enhances communication has profound effects in terms of how people can learn from each other, and how they can achieve the kind of freedoms that they're interested in. Bill Gates
