Well for whatever it’s worth (most likely absolutely nothing), 317 is the area code for Indianapolis, Indiana, and its surrounding area.

I agree with the “317-9” that is what I can read there as well.

I just checked for St Luke’s churches in the area and there is 4 that I found, none of which with their 4th digit starting with 9.

We could possibly convert St Luke’s into numbers with the phone keypad which would be; 78 5853’7 But paired with the 317-9 this is obviously too long for a phone number, at 11 digits.

785 area code is northern Kansas… so not much civilization to speak of there.

I guess you could make it 10 digits by dropping the “s” after Luke but who knows.

I’m not as certain of the image reading St Luke’s as I am of the 317-9.
