I’m not sure what you’re getting at with your two questions…canyou help me out a little? Sorry!
Ok, being filled with the Holy Spirit is not equal to salvation. The filling of the Holy Spirit is God working in a persons life. The Holy Spirit through the filling, empowerment if you will grants spiritual gifts to Chrisitans ( I Cor 12 ). Usually, the filling of the Holy Spirit occurs after one becomes a Chrisitan. But, in the case of Acts 10, the flow of the chapter is Peter having a vision where he learns that salvation is open to the gentiles too, then the Holy Spirit fills the gentiles giving them the gift of tongues. Peter and the Apostles witness this out pouring of God’s Holy Spirit on these gentiles. At that point water baptism is made avilable to the gentiles.
Now, when one is born again, that is called the indwelling of the Holy Spirit which is often a seperate event from the filling of the Holy Spirit. For example, the apostles recieved the Holy Spirit in John 20:22, “And with that he Jesus ] breathed on them and said, “Receive the Holy Spirit.”” One can only be indwelt with the Holy Spirit one time to my knowledge which is when they become born of the Spirit. The filling of the Holy Spirit ( read the book of Acts look for fill, full, upon ) can occur many times.
So, Acts 10 is an unusual case where gentiles were filled before they were indwelt or recieved water baptism.
In Pentecostal circles there is a doctrine called “baptizism with the Holy Spirit” it is based on these texts,
Luke 3:16
John answered them all, "I baptize you with water. But one more powerful than I will come, the thongs of whose sandals I am not worthy to untie. **He will baptize you with the Holy Spirit **and with fire.
I think this baptism of the Holy Spirit could be either the indwelling or filling.
I see the baptizism of the Holy Spirit in Acts as referring to the filling of the Holy Spirit, and maybe in some cases the indwelling.
Acts 1:5
For John baptized with water, but in a few days you will be baptized with the Holy Spirit."
filling,
Acts 2:38
Peter replied, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.
Both, water baptism with indwelling of the Holy Spirit followed by filling of the Holy Spirit.
Acts 8:16
because the Holy Spirit had not yet come upon any of them; they had simply been baptized into the name of the Lord Jesus.
These recieved water baptism and thus indwelling of the Holy Spirit, but have not been filled with Holy Spirit.
Acts 10:47
Then Peter said, “Can anyone keep these people from being baptized with water? They have received the Holy Spirit just as we have.”
They were filled first which is unusual, but it was as a sign to the apostles that God was indeed working among the gentiles for salvation in Christ.
Acts 11:16
Then I remembered what the Lord had said: ‘John baptized with water, but you will be baptized with the Holy Spirit.’
filling with Holy Spirit.
Eph 5:18 is a command given to chrisitans to be filled with the Holy Spirit.
The reason you should ask if they beleive that those in the OT were indwelt with the Holy Spirit is to find out if they believe in dispensationalism. Many dispensationalists teach that those in the OT were not indwelt with the Holy Spirit.
So, you are looking at two events that are called baptism.
The First is the “indwelling” of the Holy Spirit which is the born again thing. Catholic theology if I understand correctly says this happens at water baptism. The image is that of being baptised, through Christ’s death and Resurrection,
submerged under the water. Think of this one as a cup to is washed under, in the water of the Holy Spirit, a cleansing. This is the stage of joining the Body of Christ.
The Second is an event that can be repeated daily called being “filled” with the Holy Spirit and in the book of Acts is figuratively called baptism of the type where the Holy Spirit is **poured **on a christian. Think of this one as being a cup that is filled with water ( Holy Spirit ) from a pitcher of water.
1 Corinthians 12:13
For we were all baptized by one Spirit into one body—whether Jews or Greeks, slave or free—and we were all given the one Spirit to drink.
This text speaks of both events, being baptized into the body of Christ ( indwelling ) and being filled with the Holy Spirit ( drinking ).
So, one can say in the initial water Baptism one is both indwelt, cleaned inside, becomes a new being and one is empowered, filled with the Holy Spirit. After that, one can be empowered by choice everyday ( Rom 12, Eph 5:18 ).
