According to Christian humanitarian charity Aid to the Church in Need (ACN), Maronite Archbishop Samir Nassar's life was spared because he woke up from a nap to go to his bathroom on Monday.
He told ACN: "A shell fell on my bed... when I had retired for a little siesta, a few seconds at the sink saved my life!
"The bed was riddled with shrapnel."
Staff at the church feared the explosive killed Bishop Samir.
Bishop Samir told the charity: "They cried with joy when they saw me coming out alive of the smoke and rubble.
"Providence watches over his little servant, but now I am exiled like 12 million Syrian refugees who have nothing left."
It's been reported ten shells fell in areas of Damascus. Bishop Samir explained that Maronite cathedral has suffered major damage.
"The doors of the cathedral and 43 windows and doors have to be replaced, holes need to be filled, fuel tanks and water tanks need repairing, as does the electricity network, a car was damaged," he said.
"Violence is the only master, innocents are being sacrificed every day."
ACN said the Melkite Patriarchate on Straight Street, the only road mentioned in the New Testament and the place where St Paul stayed, also suffered damage when a bomb fell on the courtyard.
Also, the neighbouring Sisters of Jesus and Mary convent was partially damaged. They have asked for prayers for seven people in hospital who were injured during the bombing.
