Christianity originated from Lord Jesus Christ and is a monotheistic religion. It means they believe in only one God who has created the man and the world. The Christian religion is created on the life and teachings of Jesus. Christianity has been playing a prominent role in shaping of Western civilization since the 4th century. In general Christians share a common belief in the uniqueness of Jesus of Nazareth as a truly divine and truly human incarnate Son of God who is the savior of mankind. They believe each individual by their faith and life determines their eternal destiny - either in heaven or in hell.

Christianity is the third-largest religion of the country. Origin of Christianity is credited to Jesus Christ who is believed to be the only begotten Son of God. Jesus Christ is a teacher, the model of a virtuous life, the revealer of God, as well as an incarnation of God, and necessarily the savior of humanity who suffered, died, and was resurrected to bring about salvation from sin. In India Christianity is believed to have arrived with the coming of Saint Thomas in 52 AD. Saint Thomas arrived in Kodungallur, Kerala and established the Seven Churches and evangelized Kerala and Tamil Nadu. The second phase of Christianity was during the colonization of India which started after discovery of sea route to India by Portuguese explorer Vasco da Gama in 1498.

The true Concepts of Christianity implies that God is Jesus, God is Father, God is Love and the love of God is Redemptive. Thus, God for Christianity regards Jesus as the full revelation of what God is, God as Father, God as love that forgives, searches for the sinner, redeems him when he repents and turns to him, suffers on account of the sinful men and is always willing to pay the highest sacrifice for redeeming them. According to Christian belief Jesus ascended into heaven, and many believe that Jesus will return to judge the living and the dead, granting everlasting life to his followers. Christians call the message of Jesus Christ the Gospel "good news." Moreover, there is the concept of trinity in Christianity also. They believe that though Father, Son and Holy Spirit are three different persons, yet they are one.

The Holy Bible is the central religious text of Christianity. The `Bible` itself is a collection of books. The exact composition of the Bible is dependent on the religious traditions of specific denominations. The Christians derive their inspiration from the thirty-nine books comprising the Old Testament, and twenty-seven books comprising the New Testament.

Christians spread widely in all over the country. The religion is followed in South India, Konkan Coast, and North-East India and also in Central India. Christians present in India is most visible in the form of educational institutions, social services, and hospitals run by Christian organizations.

A great population belongs to the Christian Communities in India. Christians were divided into two major sects `The Eastern Orthodox Church` and `the Roman Martin Luther Catholic Church. Around seventy percent of Christians in India are Roman Catholics and the rest of the community belongs to mainly Protestants and Orthodox. According to the Roman Catholic Denomination, Jesus Christ was the "rock" on which a Church would be built and thus he became the first Bishop of Rome. In course of time the Roman Church started to occupy a special place among the other churches in Europe In the Roman Catholic priestly hierarchy, the Pope , who is the bishop of Rome, is regarded as God`s representative on earth. He is the supreme authority in matters of faith and morals for Catholics all over the world.

There are more than more than five million Protestants in India extending from the northern and eastern regions of the country. According to the Protestant Denomination, the Protestant missionaries also contend with Catholics, who had been doing the work of proselytisation for many centuries. Among the Protestants there were several divisions. A few of the protestant community activities included in India are the Presbyterian, Methodist, Baptist, Anglican, Mar Thoma Syrian Church, Assembly of God and the Seventh Day Adventist.

The Anglo-Indian Community is the group or sect that is descended from a European male progenitor. Anglo-Indians were brought by some of the policies of the British, Portuguese, and Dutch settlers and traders in India during the pre-independence period. Anglo-Indian culture and heritage is a new generation Christian community who are charaterised by their unique interest in continuing rich traditions, values, and culture.

The advent of Kannada Catholic Community was seen after coming of the Portuguese in India. The community prevails in Karnataka and in the 19th century, through the efforts of the Protestant missionaries, the Church was established, and Christianity gradually spread throughout Karnataka. Syrian Christian Community prevails in Kerala, and traces their origin from the time of St. Thomas, the apostle. The Syrian community in India form about one-fifth of the total Christian population of the Country.

Christians are taught about the conquest of passion, inner purity of heart and conscience, equality of all men before the eye of God and love, which fulfils all the laws of morality. Hence, Jesus taught a life of love, service to all fellowmen with the utmost sincerity of heart, which was a truly universal way of life, which is also the inmost meaning of the Hindu religious piety. Jesus could say what he did say as, for him God was love who made no distinction between the sinner and pious, between the righteous and unrighteous.
