Q. Did the apostle Paul ever have any children?
Paul seems to indicate in his first letter to the Corinthians that he has always been single. Addressing the question of whether a believer should marry, he says, “I wish that all of you were as I am. But each of you has your own gift from God; one has this gift, another has that.” His further comments indicate that what he means here is that he wishes they could all serve God with the advantages of singleness, as he does: “An unmarried man is concerned about the Lord’s affairs—how he can please the Lord. But a married man is concerned about the affairs of this world—how he can please his wife— and his interests are divided.” However, Paul does acknowledge that singleness and marriage are both callings—indeed, “gifts”—to each believer from God, and so “each person should live as a believer in whatever situation the Lord has assigned to them, just as God has called them.“
So if Paul never married, then he never had children. However, it seems that in his case, the promise of Jesus came true that “everyone who has left houses or brothers or sisters or father or mother or wife or children or fields for my sake will receive a hundred times as much and will inherit eternal life.” Even though Paul never married, and this allowed him to be “concerned about the Lord’s affairs” with undivided attention, in the very course of his work for the Lord he met Timothy, who became his close co-worker, and more than that. In his letters to Timothy, Paul addresses him as “my true son in the faith and as “my dear son.” He also calls Titus, another young co-worker, “my true son in our common faith.” So even though Paul never had children of his own, in the Lord he had at least two dear children who joined him and helped him in his mission.
