The Holy Spirit declared the identity of the child Jesus to Simeon the elder and Anna the prophetess (Luke 2:25–38).
St. John the Baptist testified of Him, saying, “Behold! The Lamb of God who takes away the sin of the world!” (John 1:36).
The Father testified of Him when He was baptized in the River Jordan, saying, “This is my beloved Son, in whom I am well pleased” (Matt. 3:17). He also testified of Him during His transfiguration before three of His disciples (Mark 9).
