Here the baptism of the Samaritans by the deacon Philip is narrated (Acts 6:5). He, however, did not impart the Holy Spirit to them.
Therefore the apostles Peter and John were sent to Samaria to impart the Spirit to them. They “came and prayed for them,” the Samaritans, “laid their hands on them, and they received the Holy Spirit.”
In the same chapter, verses 36-39, the baptism of the Ethiopian man is recounted. The baptism was performed by the same Philip.
It followed the preaching of Christ (Acts 8:35), which produced in the hearer a sincere faith in Jesus Christ as the Son of God (Acts 8:37).
After this, Philip and the Ethiopian both went down into the water, and Philip baptized the Ethiopian.

From this it is evident that in the Church of apostolic times there was both baptism in water and the imparting of the Holy Spirit through the laying on of hands (Acts 8:17-18).
These mysteries are performed to this day in the holy Orthodox Church. Only the imparting of the gift of the Holy Spirit is performed not through the laying on of hands, but through chrismation.
