[Ruy Dias de Bivar]

***He commanded a baptism that was for the remission of sins and receiving the Holy Spirit.***

And yet, Cornelius received the HOLY SPIRIT before he was baptised.
Look at the verse that Peter spoke just before the HOLY SPIRIT fell on him!

Act 10:43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.

Act 10:44 ¶ While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.

[Cronos]

Note the CONTEXT of Cornelius' baptism -- he was the FIRST GENTILE to be baptised, and this was BECAUSE the Holy Spirit did something unusual -- unlike for Jesus when the Holy Spirit descended at the time of baptism, this was different, this was the Holy Spirit talking to the Apostles telling them to preach and baptise Gentiles without first making them jews

The normal way that happened in every other place in acts and the letters is for the holy Spirit to come in baptism, and then the gifts ofthe Holy Spirit.

However, let me note -- this does not deny the efficacy of baptism, it only points out that baptism is necessary, whether before or after.
