He was the forerunner. He came to prepared the way for Jesus Christ
Because at Advent, we prepare for Our Lord's Coming, which is what St. John's ministry was for.
He was a distant relative of Our Lord, and he baptized people, to prepare them for Christ's Ministry.
John the Baptist's ministry was to prepare the way of the Lord and to introduce Jesus to the world as the Lamb of God who takes away the sin of the world. John's ministry was prophesied in the Old Testament (Malachi 3:1; 4:5-6) and he fulfilled it by establishing the baptism of repentance and the introducing Jesus to the world. Jesus' ministry mainly was to be the Lamb of God that John the Baptist prophesied about Jesus. To accomplish this ministry Jesus died for the sins of the world as prophesied by Old Testament prophets (Eg: Isaiah 53). To fulfill His ministry to die for the mankind, Jesus went through all the stages of human development (born, lived among people, etc) to be an ideal substitute for a human.
The Bible does not say anything about John the Baptist being shipwrecked. His ministry was in the wilderness.
No. They are not the same. St John the Apostle was a former fisherman who was called to be one of the twelve disciples whom Jesus taught and trained during his ministry here on earth (Luke 5:1-11). John the Baptist was Jesus' cousin, born to Elizabeth and Zacharias (Luke 1:1-80; 3:1-18) who preached repentance to the Jews prior to Jesus' earthly ministry. John the Baptist is also call the "forerunner" of Christ because of his ministry to prepare others to receive Jesus' message of salvation.
John the Baptist is noted for living off the land in the desert and wearing coarse clothing. His mission was to prepare the way for the coming public ministry of Our Lord and preach a baptism of repentance.
At the time of John the Baptist, Christianity was not yet formed. Since John the Baptist was Hebrew, he followed the Hebrew religion. Under the Hebrew religion, people from the Tribe of Levi were Priests. John's father was a Levi and also a priest. Through his bloodline, John would have been a priest, but there is no indication he worked at the temple. However, the Bible does show that John did have a ministry -- though accounts from the Bible show that John's ministry took place outside, in the open. Usually, it would be customary for John, as a Levite, to have worked at the temple, but it is not mentioned if he ever did or not.
The Sermon on the Mount was given early in His ministry immediately after being Baptized by John the Baptist - first year .
I don't think we can call it urban ministry since he conducted his preaching and baptizing in the countryside and the people came out to him from the cities and towns.
What is known in the Bible was 1) Jesus started his ministry when he was thirty years old, 2) John was approximately six months younger than Jesus, and 3) John started his ministry before Jesus did, so John began preaching some time before his 30th birthday. It's not known how long John was preaching.
John the Baptist was a prophet who preached about the coming of Jesus as the Messiah, but he was not one of Jesus's disciples. John baptized Jesus and played a crucial role in preparing the way for Jesus's ministry.
