Lay baptism

Many cultures practice or have practiced initiation rites, including the ancient Greeks, the Hebraic/Jewish, the Babylonian, the Mayan, and the Norse cultures. The modern Japanese practice of Miyamairi is such as ceremony. In some, such evidence may be archaeological and descriptive in nature, rather than a modern practice.

In Brahma Kumarism, after a probationary period of 6 months to 3 years, hundreds of young girls and virgin women are married to the religion's God in mass weddings. Their dowries are taken by the organisation after which they belong to it and are often posted at great distance from their families, unlikely to see them again. Returning to the world after doing so is very difficult for them. The practice was defended by the religion as the only way to stop the poor from dumping unwanted daughters on them.

The Ecclesia Gnostica Catholica, or Gnostic Catholic Church (the ecclesiastical arm of Ordo Templi Orientis), offers its Rite of Baptism to any person at least 11 years old. The ceremony is performed before a Gnostic Mass and represents a symbolic birth into the Thelemic community.

Akshara abyasam is a Hindu education initiation ceremony commonly held for children in Karnataka, Andhra Pradesh and Telangana.

Islam practises a number of ablution ceremonies, but none of them has the character of a religious initiation rite. Christian baptism is challenged in the Quran in the verse: "Our religion is the Baptism of Allah; And who can baptize better than Allah? And it is He Whom we worship". Belief in the monotheism of God in Islam is sufficient for entering in the fold of faith and does not require a ritual form of baptism.
