"For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek." (Rom. 1:16)

The little word "the" is a definite article and is a special kind of adjective which points to a particular or specific time, person, place, or thing. If you were standing near a large parking lot filled with cars and were asked by a friend to put some object in "a car," you would likely approach the nearest car and put the object in it. However, if the friend had said, "Put this in 'the' car," you would immediately ask, "Which one?" You would realize that the definite article "the" refers to one, and only one, car.

Similarly, when the Bible refers to "the faith" (Gal. 3:23; Jude 3), or "the church" (Eph. 1:22; Col. 1:18), it means that so far as God is concerned, there is only one faith and one church.
