The Catholic Church has never claimed that the work
of the
Holy Spirit is limited exclusively to Baptism.
Confirmation is the Catholic Church's official
prayer for the
Holy Spirit to empower a person to spread the
gospel, to
live a fervent Christian life, and share more fully
in the mission
and ministry of the Church.
Receiving the Holy Spirit in a new way, usually as
the result
of earnest, expectant prayer, is what many
Christians today
call being "baptized in the Holy Spirit."
Being "baptized in the Holy Spirit" is
actually a "release" or
a "coming to consciousness" of the power
of the Holy Spirit
who already has been given to the believer through
the
sacraments of the Church.
