I 21f feel upset at a guy 18M insisting he's in love with me by quoting the bible. Not sure how to move forward with it?

Hi, I'm 21F in 1st year college and I've known this guy Z (18M) for 2 months and 21 days. It's a bit of a mess so please bear with me.

The mess really starts sept 29 when Z asked me about having a dilemma and not knowing what to choose between what's logical, what's in his mind, and what's in his heart. He then proceeded to send me this whole message. (linked it on paste bin so this post isn't too long, let me know if I should change it). I initially thought it was about me but I didn't want to be too presumptuous or overconfident that it's about me that I pushed past that thinking and asked help from another male friend and asked him what I should tell Z (my thinking was that they're both guys so it should be all good).

My male friend's advice basically boils down to: it's either you confess or you don't, confess if you don't want to regret anything but if I (male friend) were you, then I would take this to my grave.

I then brought this to Z on sept 30, prefacing that I did get the advice from someone else but that he's not doxxed or anything like that.

Following me sending this, Z then said that he doesn't agree with the term 'confessing' because it implies that he's hiding his romantic feelings for someone else and that he's not, it's just that nobody's ever asked him before, not even the person herself. I then asked if he's gone to anyone else about this dilemma and he said he's only gone to me. My heart sank to my stomach then, but I decided to play dumb because I didn't want to hear/read it. Z then proceeded to call me bro, asking about video games and school work and I went along but ultimately became unresponsive to his messages (sept 31 to oct 8).

Then, oct 9, Z dropped another set of long messages on me. This time, coming clean that the girl he was talking about was me. This time though, he said much much more. Linked here (some parts are translated to English, but context is kept the same).

Here's what I replied a day after. It's hateful (I suppose to an extent), lots of fucks and I recognize now after a couple of hours that it might not be it. I don't really know, but it feels like I've been pushed to the edge? Still may not have been the best reply I suppose. Anyways, it gives a bit of context on this guy D which is also a classmate who I had a fight with and eventually went off on too for him rationalizing what he did when we fought and then adding that I should "wait for him (to confess) while he still gathers his courage". Z is in this mix because he's the one that told me that D likes me in the first place, and he's also the one that convinced D to message me after we fought.

Z replied a bit after, saying he didn't expect me to react so strongly and then followed it up with these 2 long ass messages.

My main thing is that I already felt like shit with his long ass messages from oct 9, but now I feel even worse with him bringing up the bible into this whole thing. I'm also a registered catholic, but I don't practice, I consider myself more like agnostic, and I have had some bad experiences with the catholic church. I want to go off on him again, tell him it's not love he's feeling, but feel like if I do, it's not only his "thoughts" I have to fight with, I'd also have to fight against what's written in the bible?

What do I even do? Do I even reply, do I just block him? It's nuts because our first sem isn't even finished and now he's doing all this.

Also, please let me know if the linked messages isn't good, I can post them on the comments instead or something.
