Incarnation

Incarnation literally means embodied in flesh or taking on flesh. It refers to the conception and birth of a sentient being who is the material manifestation of an entity, god or force whose original nature is immaterial. In its religious context the word is used to mean the descent from Heaven of a god, or divine being in human/animal form on Earth.

In the Bahá'í Faith, God is not seen to be incarnated into this world and is not seen to be part of creation as he cannot be divided and does not descend to the condition of his creatures. The Manifestations of God are also not seen as an incarnation of God, but are instead understood to be like a perfect mirror reflecting the attributes of God onto this material world.

Buddhism is a non-theistic religion, it denies the concept of a creator god or any incarnation of a creator god. Buddhism, however, does teach the rebirth doctrine and asserts that living beings are reborn, endlessly, reincarnating as Devas (gods), demi-gods, human beings, animals, hungry ghosts or hellish beings, in a cycle of samsara that stops only for those who reach nirvana (nibbana).

In Tibetan Buddhism, an enlightened spiritual teacher (lama) is believed to reincarnate, and is called a tulku. According to Tulku Thondup, there are three main types of tulkus. They are the emanations of buddhas, the manifestations of highly accomplished adepts, and rebirths of highly virtuous teachers or spiritual friends. There are also authentic secondary types as well which include unrecognized tulkus, blessed tulkus, and tulkus fallen from the path.

The incarnation of Christ is a central Christian doctrine that God became flesh, assumed a human nature, and became a man in the form of Jesus, the Son of God and the second person of the Trinity. This foundational Christian position holds that the divine nature of the Son of God was perfectly united with human nature in one divine Person, Jesus, making him both truly God and truly man. The theological term for this is hypostatic union: the Second Person of the Trinity, God the Son, became flesh when he was miraculously conceived in the womb of the Virgin Mary. Biblical passages traditionally referenced in connection with the doctrine of the Incarnation include John 3:1-21, Colossians 2:9, and Philippians 2:7-8.
