If you are just making a jack to jack, it doesn't matter. If the

The church has a 66 punchdown block for the phones (I put that in last
week) but not for the Ethernet.

The jacks have 110 punchdown terminals, and they are labeled for both
A & B but the labels don't make any sense. I'm gonna have to use a
continuity tester and figure out the pin-out (I think it's 1234 down
one side and 8765 on the other, where the outermost terminals are 4
and 5) I may do that tonight.

I've about decided to use B. If the jack is wired the way I think it
is, the orange pair (for B) goes on the inner left and the brown pair
on the right, then the green pair gets separated left and right in the
next terminals, then blue in the outermost terminals. To wire it "A",
just swap the orange and green.

If I was evil, I would put a crossover cable in the walls. ;-)

Countless web pages, probably including the manufacturer of the jacks
you are using, have color-coded diagrams of which wires go in which
slots for the A and B wiring patterns. I think the ones the Borg sells
even have a diagram on the card, or a stack of brochures from the
manufacturer. Play close attention to where it says to maintain the
twist for each pair to within a half-inch of the slots.

Now that I look at it, that wall jack diagram seems to be for the 'a'
pattern. But the pin numbers are correct, so you can just match the
colors up with the pin numbers on the 'b' diagram on the first link.

(I'm lazy, and don't have a punchdown tool any more. I just use premade
cables....)
