If all other cathedrals are built, it's probably too late... It takes a bit of guesswork/intuition.
Intuitively (based on my experiences with six city games) I would hazard a rule of thumb that says if a religion spreads before you have built all the other cathedrals, build cathedrals for the new religion as well; but if you have built all the other cathedrals already, don´t bother with the new religion...
... it´s just that it´s just so tempting to try and squeeze a bit more culture out from a few more cathedrals. Maybe I´m just too greedy
