The 4 calling birds are the four Gospels: Matthew, Mark, Luke, and John. These sing the Song of Salvation. We are up to four in the song and have reached the Gospels. Notice something else about the song so far? The first four are birds of some sort. Not sure the significance there but I am sure there is something.
The four calling birds could also mark the four presenters of the Gospel as well. Even though two were not Apostles they all present the Gospel in a unique fashion especially John. Each one does take a different type of approach in the presentation though many similarities are found. Matthew was the tax collector turned champion for Christ. He went in front of the Sanhedrin to present Jesus to them. Matthew had an inside track on many things and detailed the sermons and parables. His recording of the Gospel is where we get the Beatitudes, the Last Supper, and the Great Commission, just to name a few important details. They did not kill him like they did Stephen, guess he was protected and spoke many truths to them and probably had enough dirt on them to keep him alive.
Mark, also known as John Mark was a student/follower/scribe of Paul. Rumor has it that Mark actually wrote the Gospel first and it was used by Matthew for writing purposes. Not much is known about him except that he journeyed with Paul.
Another who worked with Paul was Luke. Luke was a Physician which explains why his telling was of great detail and possibly somewhat embellished. His writing is where we get the birth story which is read every Christmas. Luke also details more of the parables and also wrote the Acts of the Apostles.
John, oh John the Beloved. John focused on the Spiritualism and Deity of Jesus. The Gospel According to John is where we learn that Jesus is the Word made flesh who was with God at the Creation. We also find the reason Jesus was sent to us. I got my life verse from John 15:13 Greater love hath no man than he who would lay his life down for his friends. John’s Gospel concentrates of God’s Love for us through Jesus.

Today is also the Christian Feast of the Innocents. It is this day our Christian ancestors remembered the Innocent Blood of the boys killed by King Herod to try and kill Jesus. He was unsuccessful but completed his mark in history as one of the most ruthless of governor/kings ever to rule over Judea.
