Nowadays, In The New Testament, the Holy Spirit is given through three ways:
The Holy Anointing, Laying Priests’ Hands and The Holy Breath.
As for The Holy Breath, it was written in St John’s Gospel that our Lord Jesus, after His Resurrection, when He appeared to His disciples, the saints, in the upper room, He told them “As the Father has sent Me, I also send you." And when He had said this, He breathed on them, and said to them, "Receive the Holy Spirit. If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained."” (Jn 20:21-23)
In the ordination of the bishop or the priest we breathe in his face and say “Accept the Holy Spirit”, so he opens his mouth to accept the holy breath and says with the psalm “I opened my mouth and accepted myself a spirit”.
As for Laying Hands, the Holy Spirit in the time of our fathers the apostles was given through the apostles laying hands. This was mentioned in giving the Holy Spirit to the People of Samaria. The Apostles Synod in Jerusalem sent them St Peter and St John “Then they laid hands on them, and they received the Holy Spirit.” (Ac 8:14-17) And the same was done to the People of Ephesus “And when Paul had laid hands on them, the Holy Spirit came upon them” (Ac 19:7). Same applied to the Priesthood Sacrament, St Paul the Apostle said to his disciple Timothy “I remind you to stir up the gift of God which is in you through the laying on of my hands.” (2 Ti 1:6) The Holy Anointing was also known in the apostolic age. St John the Apostle says about that: “But you have an anointing from the Holy One…” (1 Jn 2:20) “… But the anointing which you have received from Him abides in you.” (1 Jn 2:27)
