Baptizing

Certain schools of Christian thought (such as Catholic and Lutheran theology) regard baptism as necessary for salvation (though not without exception), but some writers, such as Huldrych Zwingli (1484–1531), have denied its necessity. Though water baptism is extremely common among Christian denominations, some, such as Quakers, some Unitarians (in particular Unitarian Universalists), and the Salvation Army, do not practice water baptism at all. Among denominations that practice baptism, differences occur in the manner and mode of baptizing and in the understanding of the significance of the rite. Most Christians baptize using the Trinitarian formula "in the name of the Father, and of the Son, and of the Holy Spirit" (following the Great Commission), but Oneness Pentecostals baptize using Jesus' name only. The majority of Christians baptize infants; many others, such as Baptist Churches, regard only believer's baptism as true baptism. In certain denominations, such as the Eastern and Oriental Orthodox Churches, the individual being baptized receives a cross necklace that is worn for the rest of their life, inspired by the Third Council of Constantinople.
