So after Acts 1:5 all we see is baptism of the Holy Spirit? Could you please show this Holy Spirit baptism after Acts 1:5. I only know of one other instance and it was a special occasion as was the one in Acts 1.
I see more than one instance of water baptism after Acts 2.
Well after the original outpouring of the gift on the day of Pentecost is no longer referred to as baptism of the Holy Spirit, (except in retrospect) but rather baptism in the name of Jesus Christ, Acts 2:38
As you might imagine and is still evident today, not everyone kept pace with the doctrinal growth in the book of Acts or with the Apostles, especially and later, the apostle Paul.
Many of the believers, ie, those of the circumcision, still held fast to the law of Moses and its ceremonies.
Just as believers have done and continue to do, they hold onto obsolete traditions needlessly.
These same believers ended up persecuting the apostle Paul because Paul taught that we were no longer under the law for righteousness as we see in Romans... especially Galatians 2:21 righteousness does not come by the law, if it does then Christ is dead in vain
These believers sought self righteousness instead of the righteousness which is from God by believing.
We read in Philippians 3 that if anyone could have had a claim to fame by following the law, Paul did, but he rejected that for he understood and believed what he wrote in Philippians 3:9
We are made the righteousness of God in him II Corinthians 5:21, not by the law including John's baptism.
We are righteousness by the works of Jesus Christ.
