I. Confirmation in the Economy of Salvation

From The Catechism of the Catholic Church

1291
A
custom of the Roman Church facilitated the development of the Western practice:
a double anointing with sacred chrism after Baptism. the first anointing of the
neophyte on coming out of the baptismal bath was performed by the priest; it
was completed by a second anointing on the forehead of the newly baptized by
the bishop.¹⁰¹ The first anointing with sacred chrism, by the priest,
has remained attached to the baptismal rite; it signifies the participation of
the one baptized in the prophetic, priestly, and kingly offices of Christ. If
Baptism is conferred on an adult, there is only one post-baptismal anointing,
that of Confirmation.
