In infant baptism, adults called godparents make various promises on behalf of the baby until he or she is old enough to make those same promises for himself. At adult baptism those promises are made by the person being baptised, as he or she is old enough to speak for himself or herself. The promises are that the person to be baptised needs to renounce evil, say 'sorry' for the things they have done wrong, state a belief in God, and turn to Christ as their Saviour. Usually the promises are made as simple statements or questions with short responses like 'Do you turn to Christ as your Saviour?' Answer:- "I turn to Christ as my Lord and Saviour" The actual baptism is usually divided into three parts. Firstly the minister makes a sign of the cross on the forehead (sometimes in oil as this is the traditional way of the Biblical practice of 'anointing' - setting aside for God). This symbolises the pperson turning to Christ and marking them out as one of God's family. Secondly, the minister carries out a ritual washing in water of the person to be baptised, symbolising the cleansing from sin of that person. At this washing he or she will say the words " Frederick (or whatever his name is), I baptise you in the name of the Father and of the Son and of the Holy Spirit, Amen." These words reflect Jesus' great commission to baptise in this way (see the last few verses of Matthew's gospel). The minister will wash him three times with water as he states those words. In some churches (such as Roman Catholic and Anglican churches) the washing is done over a small font (like a large water basin on a pedestal) and the water splashed over the person's forehead as he stands at the font. In some churches (notably Baptist Churches) the baptism is done by 'full immersion' where a baptistry is used instead of a font ( like a large sheep-dip!) and the person ''dunked' under the water three times. Either form of baptism is valid - but the traditions of different churches differ. The final part is the giving of a lighted candle to the person baptised to symbolise their passing from 'darkness' into 'light' - as a new member of God's family. Often the candle is kept and lit at the anniversary of the person's baptism just as you would a birthday cake candle. Finally, prayers are said for the new Church member to support him or her and to ensure him or her that the whole Church family will be there for them. Some churches then give a certificatein case the person needs proof of baptism (e.g. if they one day wish to be ordained). Incidentally, one is baptised into the Christian Church - not baptised as a Catholic, Baptist or Anglican, and so, despite what some may say, once you are baptised (by making the promises and by being symbolically washed in the name of the father, Son and Holy Spirit) you are baptised, period.
Adults get baptised as an outward expression to show that they have come into faith in Christ Jesus. There are still belief differences by some groups; for example some groups believe that anyone can be baptised where other groups believe that the person should have come to a personal conscious decision of faith before being baptised.
This varies from church to church. For the most part the process is the same modelled after John the Baptist. The head is usually anointed with oil and\or water. Some people take a Christian name (either first, middle, or last) at that time. Some faiths have full body immersion for baptism, some are much lower key but a member of the clerigy anioints the person being baptised in the name of Christ and your done. Some Churches are very celebratory about the event while other either are low key or afford a measure of modesty to the event. Check with your church for details. Catholics if memory serves me correctly require Mass as part of the service. I do not recall if Communion is given immediately for adults or if a first communion\confirmation requirement is needed. Their sins are forgiven. Acts 22:16 - And now why are you waiting? Arise and be baptized, and wash away your sins, calling on the name of the Lord. Spiritually, their lives get a fresh start. Romans 6:4 - Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life. They receive the gift of the Holy Spirit. Acts 2:38 - Then Peter said to them, "Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. [Among other things, the Spirit marks the believer as belonging to God (Ephesians 1:13, Romans 8:9 & 16), protects the heart and mind against error and false doctrine (1 Corinthians 2:10-15), adds power to prayer (Romans 8:26), and intercedes with God on behalf of the believer (Romans 8:27).] The Lord adds them to the church. Acts 2:47 - And the Lord added to the church daily those who were being saved. Their name is written in the Book of Life. Philippians 4:3 - And I urge you also, true companion, help these women who labored with me in the gospel, with Clement also, and the rest of my fellow workers, whose names are in the Book of Life. They become children of God and heirs to eternal life. Titus 3:7 - that having been justified by His grace we should become heirs according to the hope of eternal life. ----
The Adult makes a statement/vow before God, Satan, their family and church, and to the World, about their dedication to God and their Salvation.
Then the pastor submerges the adult into a pool of water, river, ocean, stream and brings them back out.
This is a symbolic symbol of the "Old man" being buried and a "new man" being born.
they are now a member of the kingdom of heaven
At an adults baptism the light of Jesus passes to the Christian- often symbolised by candles.
You get to be born again as a Christian.
