More evidence that Luke, Acts, Matthew and Mark were all written before Ad70:
Acts 23:7 "As soon as he had said this, a dispute broke out between the Pharisees and Sadducees, and the assembly was divided. 8For the Sadducees say there is neither a resurrection [they were sad,you see], nor angels, nor spirits, but the Pharisees acknowledge them all."
The Saducees as a formal group didn't exist after Ad70, but are always referred to in the present tense as though they were in existence at the time of writing.
"And certain of the Sadducees, who are denying that there is a rising again, having come near, questioned him," Luke 20:27 YLT
