A. They both are–at least in most cases. That’s because they are both usually arguing over the wrong verses. As the Baptists assert, the baptism of the Ethiopian eunuch does imply immersion baptism. But it is not for the reasons immersionists, such as Baptists, usually cite and which those who baptize by sprinkling, such as Presbyterians, argue against. And the Presbyterians are right to argue against the verses the Baptists claim support their cause.
by Peter Ditzel
For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
The proponents of infant baptism seem to use this Scripture as if it were a cornerstone of their doctrine. Almost all books and articles supporting infant baptism include this verse. But does Acts 2:39 support infant baptism or does it teach just the opposite?
A. This is a common question. Some other ways that it can be asked are, “How can I know that God has chosen me as one of His children?” and, “How can I be assured of God’s love for me?” It is, in fact, a question of what theologians call assurance.
I know people who have come up with all sorts of elaborate ways to answer this question. They tell people to look at themselves and see how they have changed since the time they think they became a Christian. They tell them to look at their love for others, their Christian works, their growth in Scriptural knowledge, their better morality, how much they love the law, and so on. Others will also advise people to wait for a vision, a voice, or a feeling to know they are saved.
