Christian doctrine in the context of "Born again"

Chalcedonian Christianity is the branch of Christianity that accepts and upholds theological resolutions of the Council of Chalcedon, the fourth ecumenical council, held in AD 451. Chalcedonian Christianity accepts the Christological Definition of Chalcedon, a Christian doctrine concerning the union of two natures (divine and human) in one hypostasis of Jesus Christ, who is thus acknowledged as a single person (prosopon). Chalcedonian Christianity also accepts the Chalcedonian confirmation of the Niceno-Constantinopolitan Creed, thus acknowledging the commitment of Chalcedonism to Nicene Christianity.

Chalcedonian Christology is upheld by Roman Catholicism, Eastern Orthodoxy, Lutheranism, Anglicanism and Calvinism (Reformed Christianity), thus comprising the overwhelming majority of Christianity.

The Trinity (Latin: Trinitas, lit. 'triad', from trinus 'threefold') is a Christian doctrine concerning the nature of God, which defines one God existing in three coeternal, consubstantial divine persons: God the Father, God the Son (Jesus Christ) and God the Holy Spirit, three distinct persons (hypostases) sharing one essence/substance/nature (homoousion).

The Session of Christ or heavenly session is a Christian doctrine stating that Jesus is seated at the right hand of God the Father in Heaven—the word "session" is an archaic noun meaning "sitting". Although the word formerly meant "the act of sitting down", its meaning is somewhat broader in current English usage, and is used to refer to a sitting for various reasons, such as a teaching session, or a court or council being in session. The New Testament also depicts Jesus as standing and walking in Heaven, but the Session of Christ has special theological significance because of its connection to the role of Christ as King. The Session of Christ is one of the doctrines specifically mentioned in the Apostles' Creed, where "sitteth on the right hand of God the Father Almighty" immediately follows the statement of the Ascension.

The intercession of saints is a Christian doctrine that maintains that saints can intercede for others. The invocation of the saints is the practice of persons requesting saints to intercede for them; the comprecation of saints is the practice in which Christians ask God for a share in the prayers offered by the saints. The practice of the invocation of the saints is held by the Catholic Church, Eastern Orthodox Church, the Assyrian Church of the East, the Oriental Orthodox Churches, and some Lutherans and Anglicans (chiefly those of Evangelical Catholic or Anglo-Catholic churchmanship, respectively). The Lutheran Churches and the Anglican Communion accept the doctrine of the intercession of the saints, holding that the saints (living and in heaven) pray for the Church; the practice of the comprecation of saints is accepted by these traditions, though the invocation of the saints is generally rejected by these Christian denominations (apart from certain Evangelical Catholics and Anglo-Catholics).

To intercede is to go or come between two parties, to plead before one of them on behalf of the other. In ecclesiastical usage both words are taken in the sense of the intervention primarily of Christ, and secondarily of the Blessed Virgin Mary and the angels and saints, on behalf of men and women.

To be born again, or to experience the new birth, is a phrase, particularly in evangelical Christianity, that refers to a "spiritual rebirth", or a regeneration of the human spirit. In contrast to one's physical birth, being "born again" is distinctly and separately caused by the operation of the Holy Spirit, and it occurs when one is baptized in water (as in John 3:5 and Titus 3:5). While all Christians are familiar with the concept from the Bible, it is a core doctrine of the denominations of the Anabaptist, Moravian, Methodist, Baptist, Plymouth Brethren and Pentecostal churches along with evangelical Christian denominations. These churches stress Jesus's words in the Gospels: "Do not be astonished that I said to you, 'You must be born from above.'" (John 3:7). Their doctrines also hold that to be "born again", and thus "saved", one must have a personal and intimate relationship with Jesus Christ.

The term born again has its origin in the New Testament. In the First Epistle of Peter, the author describes the new birth as taking place from the seed which is the Word of God. In the Gospel of Luke, Jesus himself refers to the Word of God as the seed.
