While acknowledging that "the New Testament contains no explicit record of a transmission of Peter's leadership; nor is the transmission of apostolic authority in general very clear," it considers that its doctrine has a developmental history and that its teaching about matters such as the Trinity, the divinity of Christ, and the union of his two natures in a single person developed as the result of drawing out from the original revealed truth consequences that were not obvious at first: "Thanks to the assistance of the Holy Spirit, the understanding of both the realities and the words of the heritage of faith is able to grow in the life of the Church 'through the contemplation and study of believers who ponder these things in their hearts'; it is in particular 'theological research [which] deepens knowledge of revealed truth.'" Accordingly, it would be a mistake to expect to find the modern fully developed doctrine of papal primacy in the first centuries, thereby failing to recognize the Church's historical reality. The figure of the pope as leader of the worldwide church developed over time, as the figure of the bishop as leader of the local church seems to have appeared later than in the time of the apostles. That the Christian scriptures, which contain no cut-and-dried answers to questions such as whether or not there is forgiveness for post-baptismal sins, and whether or not infants should be baptized, gradually become clearer in the light of events, is a view expressed, when considering the doctrine of papal primacy, by Cardinal John Henry Newman, who summed up his thought by saying: Writers such as Nikolay Afanásiev and Alexander Schmemann have written that the phrase "presiding in agape", used of the Church of Rome in the letter that Ignatius of Antioch addressed to it in the early 2nd century, contains a definition of that Church's universal primacy; but the Catholic writer Klaus Schatz warns that it would be wrong to read, as statements of the developed Catholic teaching on papal primacy, this letter and the even earlier First Epistle of Clement (the name of Clement was added only later), in which the Church of Rome intervenes in matters of the Church of Corinth, admonishing it in authoritative tones, even speaking in the name of God. It was only later that the expression of Ignatius of Antioch could be interpreted as
