So you allow priests to research fireballs, magic missiles, read magic
and so on? Or let wizards create healing spells or spells that allow
comminication with a deity (i.e. augery)? No, of coarse not.

While the effects of some spells might look the same, there is a
fundamental difference between wizard and priestly magic. One of those
things is ley-lines. When a priest casts a detect magic, he is not able
to detect the school of magic, only the sphere. Why? Because he is not
familiar with the school thing. A priest is not familiar with how
ley-lines work, as you yourself pointed out in a discussion on a message
board. He would not even know where he is looking for.

As a side note, wizardly divination magic is on a completely different
area as priestly. Wizards have spells as 'magic mirror' and
'clairaudience'. Priests have spells as 'augery' and such. So even here
there is a difference between the two. Though both indeed have the
'detect' spells.
