And I also baptized the household of Stephanas
The same name with "Stephanios", or "Stephanio" in Pliny F5. Before he says he had baptized none but Crispus and Gaius; but recollecting things, he corrects himself, and observes, that he had also baptized the household of Stephanas, who by the Greek writers is thought to be the same with the jailer baptized by the apostle at Philippi, but was now removed from thence to Corinth, and was become a famous and useful man there. No argument can be formed from the baptism of his household in favour of infant baptism, since it must be first proved that he had any infants in his family, and that these were baptized; and if his household and the jailer's are the same, it is certain that his household were such who were capable of having the word of God spoke to them, and who actually did believe in God. And if they were not the same, yet it is clear that this household of Stephanas consisted of adult, converted, and very useful persons; they were the firstfruits of Achaia, and had addicted themselves to the ministry of the saints, ( 1 Corinthians 16:15 ) .
Besides,
that is, the above mentioned persons,
I know not whether I baptized any other;
meaning at Corinth, for he might have baptized, and doubtless did baptize many more in other places, for anything that is here said to the contrary: of this he would not be positive; for though he might fully know, and well remember, on recollection, who, and how many, were baptized by him with his own hands there, yet he could not tell but that some persons might have removed thither, and become members of the church in that place, who had been baptized by him elsewhere.
