There has been an extended debate over the nature of the Sacrament of Baptism that's gone on in the comments section of this blog this past week. For Pentecost Sunday, then, here's the command to be baptized that the Apostle Peter gave those gathered under his preaching on that first day of Pentecost, followed by Calvin's comment on that baptism...
Now when they heard this, they were pierced to the heart, and said to Peter and the rest of the apostles, âBrethren, what shall we do?â
Peter said to them, âRepent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit. For the promise is for you and your children and for all who are far off, as many as the Lord our God will call to Himself.â (Acts 2:37-39)
"Each of you be baptized...": Although in the text and order of the words, baptism doth here go before remission of sins, yet doth it follow it in order, because it is nothing else but a sealing of those good things which we have by Christ that they may be established in our consciences... (Calvin's commentary)
