Baptism and Latin confirmation were separated due to insistence that the bishop must administer it. Pope Innocent I (d. 417) instituted the change to oil administered only by the bishop suggesting the Paraclete Spirit is given and only through the bishop.
Originally the bishop gave all the sacraments of Christian initiation at once. It was difficult for the bishop to get to all locations in a timely fashion so in the west the priest would baptize and the confirmation came later from the bishop, whereas in the east the priest used the oil blessed by the bishop. East and west started to diverge so that the west began to emphasize the connection with the bishop and the east the nurturing of the Holy Spirit. Therefore the east kept the initiation intact.
Hippolytus’ Apostolic Tradition (earliest Verona edition 215 A.D.) describes this original initiation practice in this order:
Baptism
- bishop makes oil of thanksgiving and oil of exorcism
- anointing with oil of exorcism
- nude baptism (by triple immersion)
- anointing with oil of thanksgiving (then dry and get dressed)
Confirmation/Chrismation
5. then in the church, bishop says dismissal rite over the neophytes: “Lord God, you have made them worthy to receive remission of sins through the laver of regeneration of the Holy Spirit, etc.”
6. laying on of hands together with oil
7. sealing with oil on the forehead
8. the kiss of peace prayer
Eucharist
9. deacons bring oblation (bread and wine, water, milk, and honey)
10. the oblation is blessed
11. the milk and honey are mixed together
12. the bread is distributed
13. each tastes of the water, milk, and wine, three times.
