Pulpit is a speakers' stand in a church. In many Christian churches, there are two speakers' stands at the front of the church. Typically, the one on the left (as viewed by the congregation) is called the pulpit. Since the Gospel lesson is often read from the pulpit, the pulpit side of the church is sometimes called the gospel side.
The other speaker's stand, usually on the right (as viewed by the congregation), is known as the lectern. The word lectern comes from the Latin word "lectus", past participle of legere, meaning "to read", because the lectern primarily functions as a reading stand. It is typically used by lay people to read the scripture lessons (except for the Gospel lesson), to lead the congregation in prayer, and to make announcements. Because the epistle lesson is usually read from the lectern, the lectern side of the church is sometimes called the epistle side. In other churches, the lectern, from which the Epistle is read, is located to the congregation's left and the pulpit, from which the sermon is delivered, is located on the right (the Gospel being read from either the center of the chancel or in front of the altar).
