That is because of the people like the Jailor, and Lydia who are said that their whole households were baptized had no infants there.
Isn't that correct?
The bible authors stated
Lydia: And when she and her household had been baptized, she urged us, saying, “If you have judged me to be faithful to the Lord, come into my house and stay.” And she prevailed upon us.
The jailer :
- In the same hour of the night, the jailer washes the stripes of Paul and Silas, and is baptized along with all his family
- He then brings Paul and Silas into his home, feeds them, and rejoices that he and his family have believed in God
And Stephanus... Paul says,
1 Corinthians 1:16 “I did baptize also the household of Stephanas.”
