The immersion of baptism is symbolic; it symbolises someone being totally washed by the blood of christ. I think that it is better to have a complete spiritual immersion and it doesn't really matter if baptism is full immersion or not. Baptism is merely a physical desicion that you want to be washed clean by christ so yeah, i dont think there is anything different from a full imersion and a half-immersion.
In Christian denominations, baptism is a symbol of being completely cleansed. There are two main methods: full immersion, and the pouring water on the head. A number of denominations practice full immersion baptism (LDS, Baptists), where the whole body is briefly immersed in water. Sprinkling is the term given to the mode of pouring by those who do not believe that it is a legitimate baptism.
Jews do not have baptism. It is a Christian observance.
You should be baptized by immersion as an outward sign of your inward faith.
To give whole self god
The Orthodox Church believes in baptism by triple immersion in water. It does not allow sprinkling or aspersion.
It is called immersion.
Read Romans 6
Because, as the Bible says, we are "buried with Him by baptism unto death". Immersion is the representation of being buried in the earth.
Full water immersion
Usually by sprinkling water on the head or by immersion in water.
Sometimes, nowadays, the Roman Catholic Church actually does baptize by immersion. It has been an option since liturgical reforms after the Second Vatican Council, and many churches built or remodeled since then have rather large baptismal fonts precisely for Baptism by immersion. Nonetheless, in most places, Baptism by immersion is not very popular in Catholic Churches, as opposed to Baptism by pouring water on the head. Probably Baptism by immersion fell into disuse in the Catholic Church because it is messy, and dry-cleaning silk vestments after they have been immersed in water can be impossible, or at least expensive. Plus, many people, especially in colder countries have regarded baptism by immersion as unhealthy for themselves and their infant children. It is interesting to note that not all Catholics are Roman Catholics, and that Eastern Rite Catholics never stopped baptizing by immersion.
Same way as infants with water poured over head. Some churches will do full immersion, where the adult enters a pool knee to waist deep and their full body is dunked.
