What does initation have to do with Sikhs?

Answer 1

I don't think Sikh's have any relivation to the Christian initiation but if you meant "what is the Sikh initiation?" is here is your answer:

The most important rite in the life of the Sikh is initiation into the Khalsa, or brotherhood. The present ceremony was instituted by the tenth Guru, Guru Gobind Singh, in 1699. At this time, Sikhs were in danger from attacks and total destruction, and he felt that a brotherhood of Sikhs was needed to fight for the defence of justice and the Sikh religion. Those who wish to be initiated into the Khalsa, both men and women, should have reached an age of responsibility (usually 14-16), must be in possession of the five Ks (kesh - uncut hair, kangha - comb, kirpan - sword, kaccha - short trousers, kara - steel bracelet) and should be attempting to follow the Sikh way of life.The initiation ceremony, known as Amrit Sanskar, Pahul or Amrit Parchar, usually takes place in the gurdwara (Sikh Temple) but may be performed anywhere as long as the Guru Granth Sahib, the Sikh Holy Book, is present. The ceremony itself is conducted by five members of the Khalsa, who may be male or female, but must be devout Sikhs in possession of the five k's and physically well.The initiation ceremony begins with the opening of the Guru Granth Sahib, then one of the five presiding over the ceremony outlines the principles of the Sikh faith to the candidates and asks if they are willing to accept them. Amrit, the baptism nectar made from a mixture of water and sugar pellets, is then prepared. Each of the candidates says 'Waheguru ji ka Khalsa, sri Wahegur ji ki Fateh' which means 'The Khalsa is of God, the victory is to God', then drinks a handful of the amrit. It is also sprinkled on their eyes and hair, and each of these acts is repeated five times. The Mool Mantra, a sacred chant composed by Guru Nanak which summarises the basic beliefs of Sikhism is then read, and the initiates are told they are now, as members of the Khalsa, children of Gobind Singh and his wife Mata Sahib Kaur.The ceremony ends with the offering of Ardas, a general prayer used at the conclusion of services and the distribution of karah parshad, which is sweet food made from flour, sugar and gee. Its distribution to all present at the end of every Sikh service symbolism universal brotherhood.
