To be frank, it is not.
Can you cite any passages where Jesus sits and dines with sinners during their sin? Or where he lets their sin go without calling them to repentance?
If one truly thirsts for God, they will strive to abide by His teachings. Notice I did not say will be successful in abiding, just that they at least strive to be better.
Jesus is there for us all. If we reject Him, He will simply go away from us. He will not force us to be with Him, nor will He forget His teachings so that we will “feel better.”
Calling sin for what it is, is not uncharitable, it is a true work of mercy. I suggest you revisit the Corporal and Spiritual Works of Mercy.
Did I say Our lord dined with sinners during their sin? No. Did I say He did not call people to repentance? No. You seem to have some eisegesis going on in your reading of me, too.
I said that Our lord saved the prostitute
before calling her to repentance, and He did so unconditionally. I said He ate with sinners before calling them to repent. And in some cases, if I remember correctly, they repented without Him even needing to make such a call; His mere presence was enough.
The fact that people not yet disagree with Catholic teaching, does not mean they do not strive to know God and live by His will. It does not mean they do not thirst. If they’re met with a cold shoulder by Catholics, they are effectively denied the possibility to ever satisfy that thirst.
Lastly, I never said we should not call sin for what it is. I said there must be something very wrong with our pastoral approach. The problem here is that many seem to have a binary understanding of this - as if the only choices are to choose a hard line or throw doctrine out the window; to harshly and loudly condemn, or completely and uncritically approve. This is also reflected by the fact that I find myself seen as liberal by conservatives, and as conservative by liberals; people seem unable to fathom that not everything can be represented as “either/or”.
I say there must be another way. Currently, conservatives are alienating those who struggle with sin, while liberals compromise doctrine. There must be a way to do neither, but I do not presume to have the answer to this.
Lastly, pointing to the Corporal and Spiritual Works of Mercy is too simple. To admonish sinners can be done charitably, in a way that brings people closer to Christ, but it can also be done with complete disregard of the person and their struggles, in which case it will alienate people from the Church and Christ. In the latter case it is no longer a Work of Mercy, but may well be a sin, and a grave one at that. Sadly, charity in our times is often written off as “political correctness” and the like.
