What is baptism?
Pope Francis' address concerning baptism per reporter Carol Glatz:
"...it is through baptism that 'we become members of the body of Christ and the people of God." "...the gift of grace is passed on with each person's rebirth through baptism." Pope: Persecuted Christians must hunker down, hold tight to God, hope - Catholic Philly
Baptism contributes to rebirth.
Baptism (etymology):
"The English word baptize comes directly from the Greek verb transliterated baptiz? Likewise the noun baptism is from the Greek noun transliterated baptisma. Many believe that baptizo is properly translated 'immerse' or 'dip' as into water. "http://www.theopedia.com/Baptism
Baptism involves immersion.
Baptism (Bible):
"And so John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins. The whole Judean countryside and all the people of Jerusalem went out to him. Confessing their sins, they were baptized by him in the Jordan River... And this was his message: 'After me comes the one more powerful than I, the straps of whose sandals I am not worthy to stoop down and untie. I baptize you with water, but he will baptize you with the Holy Spirit." (Mark 1:4-8 NIV)
John's immersion utilizes water and Jesus' immersion employs the Holy Spirit.
Baptism (Jesus):
“You don’t know what you are asking,' Jesus said. 'Can you drink the cup I drink or be baptized with the baptism I am baptized with?” (Mark 10:38 NIV) (See Matthew 26, Mark 14 and Luke 22 regarding Jesus' cup)
Jesus' personal immersion involves suffering and death.
Baptism (disciples):
"Then Jesus came to them and said, 'All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age." (Matthew 28:18-20 NIV)
The disciples are to immerse believing others.
