Has the Vatican ever acknowledged that the New Testament may be missing key parts of Jesus' life?

While acknowledging that the Gospels likely contain **most** of the key events of Jesus' life... > Has the Vatican ever acknowledged that the New Testament may be missing **some** key parts of Jesus' life? Emphasis: The original authors of the Bible, who trace their lineage to the Evangelists, did the best they could to compile accounts of the *key* parts of Jesus' life, they could not (and in fact did not) bear witness to Jesus' entire life. And consequently, they may have unknowingly omitted key parts of His life.
