Depends on what type of baptism. The first "baptisms" mentioned in the New Testament of the Christian Bible were Jews going to John (the cousin of Jesus). John was performing ceremonial dunking of Jews in the Jordan River - as Jews practiced full immersion purification in a Mikveh (collection of water in Hebrew). John performed these ritual immersions following a tradition of Zav - using flowing water vs. an indoor pool.
Jesus, John the Baptist, and Paul, as good Jews, proclaimed that they were fully observant of the Law, and the Law described purification as immersion.
Following this standard of baptism, pietist Christians like the Dunkers and their progeny (Brethren Church, Church of the Brethren, etc) practice full immersion baptisms. Baptists also perform full immersion baptisms. These groups practices meet the requirements of the Law, as followed by Jesus and John. Another feature of a baptism under the Law and following the example of Jesus and John the Baptist is that the person being purified chooses to be purified. This is in contrast with some practices of non-consenting infants being "baptised".
Many Christian groups like Catholics and Lutherans only sprinkle a little water onto the person desiring purification through baptism. The Christian groups who only sprinkle also "baptise" infants and others under the age of consent, who are not able to consent or agree or volunteer for the ritual purification. It is up to the individual to decide if sprinkling non-consenting babies qualifies as following the Jesus and John the Baptist's example of a full immersion, ritual Jewish Mikveh or Rav. People who follow both the spirit of the Law and the letter of the Law consider full immersion baptisms by consenting adults to fit Jesus and John the Baptist's examples.
Depending on the denomination or church, baptism can be practiced in a number of places. Some believe that baptism can only be performed in a special font dedicated for that purpose, which is usually located in the sanctuary of a church. Others believe that baptims can be performed anywhere there is water, such as a lake, river, or swimming pool.
Yes, there are baptisms that are practiced in the Buddhist religion.
Jesus
Infant baptism is practiced in churches, as they say that nobody should be lost.
Protestant and Catholic
If you refer to Believer's Baptism, as practiced in Baptist churches, it is symbolic cleansing and rebirth into new life in Christ Jesus.
In Protestant churches where infant baptism is practiced, a candle represents the light of Christ entering the world through the newly baptized.
This practice started with Anabaptist. It is practiced by most churches called Baptist today.
One obvious religious belief would come from the name Anabaptist itself. Which means to Baptize again. Anabaptist did not believe in infant water baptism but in believer water baptism. They hold that baptism is an act of obedience to Christ on the part of the believer and not an act of obedience to Christ on the part of the parents. So they practiced believer water baptism, to their own peril, at the time of the early reformation (1500's) when infant water baptism was widely held and practiced as a sacrament of the church. Withholding baptism from your infant children was a grave mortal sin on par with condemning your children to Hell should they die before being baptized. Anabaptism is still held today by members of the various Baptist and Mennonite churches. Anabaptism has come to mean more the practice of believer water baptism.
Probably in a similar way as is still practiced in the Eastern Rites: that is, it was the second half of baptism, and was administered immediately following baptism. A vestige of this survives in the Latin Rite, where there is still an anointing with Sacred Chrism immediately after Baptism. So it would have been the anointing at the end of the initiation ceremony when the Apostles administered Confirmation.
The Rite of Baptism in most Christian churches involves Holy (blessed) Water and Holy (blessed) Water. Some denominations use springs or streams, or even a bathtub filled with water--these are blessed by the clergy just before the Baptism. Full immersion (indoor or outdoor) for adult Baptism is practiced in many denominations; other denominations use a Baptismal font (especially for infant Baptism) or sprinkling of Holy Water on the person's forehead.For example, a disabled child or bedridden adult would not be denied Baptism just because they cannot be dunked or immersed in water. The Rite of Baptism is not to exclude, but to include people into the Family of God.
Anabaptists were against infant baptism
While Graham supports believer's baptism, he also stated that infant baptism was OK, because it was practiced throughout history. All of His own children were reportedly baptized as infants, probably due to his wife, Ruth, having been a daughter of Presbyterian missionaries.
