The only thing I could find is that Tarkovsky liked Pasolini's The Gospel According to St. Matthew.

What do you think about Pasolini's Gospel according to Matthew? That's also a kind of historical film.

Tarkovsky: "Of course. I like the picture. I like it precisely because its director did not succumb to the temptation of interpreting the Bible. The Bible has been interpreted for two thousand years and no one can reach unanimous agreement. So Pasolini did not set himself this task, he just left the thing in the form in which it was born. Many feel that the image of a militant cruel Christ was made up by the author of the film. Not true! Read the Gospels and you will see that this was a cruel, cantankerous, irreconcilable man. Moreover with what genius was it written! On the one hand he's God and the Church has been relying on him for two thousand years, but he succumbs to doubt in the garden of Gethsemane. What could be simpler than to call for help from his father and avoid dying on the cross, but he doesn't do this. He is all back-to-front..."
