The teachings of the Catholic Church on the Holy Spirit might be summarized with the following:
- From the very beginning until the end of time, when the Father sends the Son, the Father also sends the Spirit, who unites us to Christ in faith so that as adopted children we can call God "Father (CCC 742).
- The Holy Spirit builds, animates, and sanctifies the Church (733).
- The Holy Spirit restores to the baptized the divine likeness lost in sin, invites them to participate in the divine life of the Holy Trinity, and sends them forth to bear witness to Christ (734-747).
