John the Baptist, also called John the Precursor (gr. Πρόδρομος) is a saint and a prophet of Christianity.

He was a contemporary of Jesus Christ and it is considered that his early teachings were to prepare the world for the coming of the Messiah (John the Precursor – gr. Πρόδρομος). He first recognized Jesus as the Messiah and baptized him, thus marking the beginning of Jesus’ ministry.

John's teachings were very powerful and he was eventually imprisoned by Herod who was afraid that he might lead a rebellion. Herod later had him executed by decapitation.

As a biblical figure he is found in both the Old and New Testament. In the Old Testament he is called a “Prophet” and in the New Testament, “Baptist” or “Precursor”.

The four Evangelists refer to him.
