Two men went up to the temple to pray

"one was a Pharisee
and the other was a tax collector.
The Pharisee took up his position
and spoke this prayer to himself,
'O God, I thank you
that I am not like the rest of humanity
greedy, dishonest, adulterous
or even like this tax collector.
I fast twice a week,
and I pay tithes on my whole income.'

"But the tax collector stood off at a distance
and would not even raise his eyes to heaven
but beat his breast and prayed,
'O God, be merciful to me a sinner.'"

(Luke 18:10-13 - from today's Gospel)
