Re: Should Babies Be Baptized?
You are making a fundamental error of logic - that the absence of evidence is evidence of absence.
It is simply not logically correct to conclude that infant baptism is "inappropriate" simply because the Bible never affirms it.
There are plenty of things that are never affirmed in the Bible that are nevertheless true and / or appropriate.
The OP asserted that infant baptism is not Biblical. One can show that position to be false without having to make a positive case for infant baptism.
The Bible does not give us "clear" evidence of the practice of infant baptism. There is neither an absolute statement in either way (one that specifically includes or excludes children from baptism). Thus, a historian looking to determine whether the Church practiced baptism, we must take the neutral position within the Bible, using those citations that speak of "whole families" as a clue that opens the possibility.
Next, we look at what the Church wrote in addition to what the Church wrote from the hand of Paul and Peter and James. Again, to the historian looking for the answer, it doesn't matter whether the writer was an apostle, but only if the person gives a reliable witness to the practice of Christianity. It does not matter whether the source is "inspired" or not. We are looking for whether the practice occured.
Here are some historical witnesses to the practice:
"And many, both men and women, who have been Christ's disciples from childhood, remain pure and at the age of sixty or seventy years..."
Justin Martyr, First Apology, 15:6 (A.D. 110-165).
"And when a child has been born to one of them, they give thanks to God [baptism]; and if moreover it happen to die in childhood, they give thanks to God the more, as for one who as passed through the world without sins."
Aristides, Apology, 15 (A.D. 140).
"Polycarp declared, 'Eighty and six years have I served Him, and He never did me injury: how then can I blaspheme my King and Saviour?"
Polycarp, Martyrdom of Polycarp, 9 (A.D. 156).
"For He came to save all through means of Himself--all, I say, who through Him are born again to God--infants, and children, and boys, and youths, and old men."
Irenaeus, Against Heresies, 2,22:4 (A.D. 180).
"I, therefore, brethren, who have lived sixty-five years in the Lord."
Polycrates, Fragment in Eusebius' Church History, V:24:7 (A.D. 190).
"And they shall baptise the little children first. And if they can answer for themselves, let them answer. But if they cannot, let their parents answer or someone from their family."
Hippolytus of Rome, Apostolic Tradition, 21 (c. A.D. 215).
"[T]herefore children are also baptized."
Origen, Homily on Luke, XIV (A.D. 233). "For this reason, moreover, the Church received from the apostles the tradition of baptizing infants too."
Origen, Homily on Romans, V:9 (A.D. 244).
As noted by the "Apostolic Traditions" and Origen, the practice is traceable to the Apostles. Note the several witnesses that speak of being a follower of Christ since childhood, which further corroborates the witnessed made in the third century. A follower of Christ is naturally a baptized individual, since it is at THAT point where one is united with the Death and Resurrection of our Lord Jesus Christ.
Thus, from a historical point of view, there is very little to show that the Church as a whole REJECTED infant baptism, but indeed practised it. What prevents people from seeing this is a stubborn adherence to "sola scriptura" applied to history and theology.
Next, such people will tell us that the Great Wall of China did not exist, because it wasn't in the Bible...
