The difference between the Pharisee and the Publican is that, one asked for MERCY.
“I say to you, that he will quickly revenge them. But yet the Son of man, when he cometh, shall he find, think you, faith on earth? Dico vobis quia cito faciet vindictam illorum. Verumtamen Filius hominis veniens, putas, inveniet fidem in terra?
9 And to some who trusted in themselves as just, and despised others, he spoke also this parable: Dixit autem et ad quosdam qui in se confidebant tamquam justi, et aspernabantur ceteros, parabolam istam :
10 Two men went up into the temple to pray: the one a Pharisee, and the other a publican. Duo homines ascenderunt in templum ut orarent : unus pharisaeus et alter publicanus.
11 The Pharisee standing, prayed thus with himself: O God, I give thee thanks that I am not as the rest of men, extortioners, unjust, adulterers, as also is this publican. Pharisaeus stans, haec apud se orabat : Deus, gratias ago tibi, quia non sum sicut ceteri hominum : raptores, injusti, adulteri, velut etiam hic publicanus :
12 I fast twice in a week: I give tithes of all that I possess. jejuno bis in sabbato, decimas do omnium quae possideo.
13 And the publican, standing afar off, would not so much as lift up his eyes towards heaven; but struck his breast, saying: O God, be merciful to me a sinner. Et publicanus a longe stans, nolebat nec oculos ad caelum levare : sed percutiebat pectus suum, dicens : Deus propitius esto mihi peccatori.
14 I say to you, this man went down into his house justified rather than the other: because every one that exalteth himself, shall be humbled: and he that humbleth himself, shall be exalted. Dico vobis, descendit hic justificatus in domum suam ab illo : quia omnis qui se exaltat, humiliabitur, et qui se humiliat, exaltabitur.”’St Luke 18:10
Divine Mercy is the last devotion given before the second coming.
