Blasphemy and Baptism

I have heard several non-church of christ teachers, baptist or wesleyan, say that COC teaching on baptism is satanic. But calling a work of the Holy Spirit satanic is blasphemy of the Holy Spirit.

1Co 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.

Since baptism is “by the Holy Spirit” it is blasphemy to call it satanic. Those poor evangelicals who have taught it have never forgiveness.

Some have said this is Holy Spirit baptism but the phrase "by the spirit" is also used in v 1-3 of chapter 12, it signifies origin of our confession and origin of baptism.

Peter was speaking by the Spirit in Acts 2:38. A verse baptists have called a satanic teaching if saying it is for the remission of sins.

Have they committed Blasphemy of the Holy Spirit? probably so.
