Baptizing the dead means that you are speaking for someone who has already made their choice in life and is now in death. We cannot make that choice for them.
Baptizing infants is about honoring the covenant with God made through Abraham about our families and made through Christ which enlivened this covenant. Further, it is about placing our children, just as they did in Scripture, into the covenant. Now only that, it’s Scriptural and has a solid foot in Christian Tradition.
Plus, Zwingli said it was okay in his refutation of the Anabaptists…
“…There were infants also under the cloud, yet no individual mention is made of them. All crossed the sea. Yet the infants could not have crossed. Therefore they crossed who did not, but were borne (carried) by those who did. …All were baptized unto Moses…therefore, not only adults, but infants also, were baptized unto Moses. For if they who were infants at the crossing of the Red Sea were not baptized, the apostle did not speak correctly in saying: All were baptized unto Moses, for they were, as I have just said, the fathers of their posterity.”
“The Hebrew children were all baptized in the cloud and in the sea, just as are ours. Paul, in the passage cited, tends in no other direction than to prove that they are as much initiated by our sacraments as we ourselves. It follows therefore, first, that in Paul’s time it was the custom of the apostles to baptize infants; second, if anyone contradicts it he vitiates the opinion of Paul.”
Which leads me to believe that Jim is really an Anabaptist…
