Mark 13-16

I had never noticed the similarities of the questioning  words of Caiaphas and Pilate to Jesus in Mark's gospel  (Mark 14:60 and 15:4).
14:60 -"Have you no answer? What is this that they are testifying against you?"
Mark 15:4 - 4 "Have you nothing to say? See how many charges they are bringing against you!"
Both men were amazed at the silence. Was it because they both knew the charges were baseless? Or was it because they had never encountered persistent silence in any other person they had accused?
The words of one other man stand out in this passage: the centurion at the cross. This was not the first centurion that Jesus had encountered. And I find it interesting that both officers admired Jesus. But the words of this second soldier was accurate in one way his lack of understanding blinded him to another truth. The centurion confessed Jesus' relationship to God: 
Mark 15:39 - "Truly this man was God's Son!"
Yet, he missed the mark in marking the confession in past tense. Even as he hung dead on the cross Jesus IS the Son of God. Not even death could rob that title from his crown.
