The New Testament is saturated with the title “Son of God.” So are our church documents, such as confessions, creeds and statements of faith. The church I used to Pastor, for example, had a statement of faith which read, “we believe that the Lord Jesus Christ, the eternal Son of God, became man.”
Christians from more Reformed backgrounds do not use “statements of faith”; they are explicitly confessional. Thus, we have the Second London Confession (1677) which affirms that “it pleased God in his eternal purpose, to choose and ordain the Lord Jesus his only begotten Son.”1
As we journey further back in time, the Apostle’s Creed, for example, reads, “I believe in Jesus Christ, his only Son, our Lord.” Notice the creed does not explain the title; it simply states as a matter of fact that Jesus is God’s “only Son.” The Nicene-Constantinople Creed does the same thing. “Also, we believe in one Lord; Jesus, Messiah, the unique Son of God.”2 The phrase here is τὸν uἱὸν τοῦ Θεοῦ τὸν μονογενῆ; a phrase many Christians know better as “the only-begotten Son of God.” Read more about What Does "Son of God" Mean?
