The Holy Spirit came upon Cornelius when he was listening to Peters sermon. Before water baptism. If water baptism is how the Holy Spirit is given then how did Cornelius receive it before water baptism?
Similar to the way that Saul did in the Old Testament. In my opinion, St. Cornelius received a gift of the Holy Spirit, speaking in tongues, in order to show St. Peter and the other Christians, that God was ready to include Gentiles in His plan of salvation. That is certainly how St. Peter understood it, because he said:
Acts 10:46 For they heard them speak with tongues, and magnify God. Then answered Peter, 47 Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? 48 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
In my opinion, if Baptism were not necessary for salvation, St. Peter would not have said that. He would have, instead, said, "“All have seen that God has saved these Gentiles because of their faith! They have believed and so are now saved! God be praised!”
There would have been no need for him to mention baptism, at all.
Maybe this was what Paul was talking about in Galatians and Ephesians when he said you received the Spirit by faith/belief.
Except that Scripture mentions being baptized many times and the references are about water baptism.
1 Peter 3:21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
Acts 8:36 And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?
John 3:22 After these things came Jesus and his disciples into the land of Judaea; and there he tarried with them, and baptized. 23 And John also was baptizing in Aenon near to Salim, because there was much water there: and they came, and were baptized.
So, unless you have St. Paul contradicting Scripture, Baptism is assumed to be by water.
I believe that we will all appears before the judgement seat of Christ but those who are “in Christ” will be judged on Christ Righteousness and not our own.
Which contradicts Scripture which says:
2 Corinthians 5:10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.
And again:
Romans 2:6 Who will render to every man according to his deeds: 7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life: 8 But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
