A manuscript was, traditionally, any document written by hand. Once practical typewriters became available, typewritten as opposed to being mechanically printed or reproduced in some indirect or automated way.

The Christian doctrine of the Trinity (Latin: trinus "threefold") holds that God is one God, but three coeternal consubstantial persons or hypostases. These being the Father, the Son (Jesus Christ), and the Holy Spirit - as "one God in three Divine Persons". The three Persons are distinct, yet are one "substance, essence or nature" (homoousios).
