It's not exactly an annoying saying, but rather an annoying habit.
My former instructor used to try and place his religious beliefs in his martial arts training. He tried to equate the "3 Battles" aspect of Sanchin to the Holy Trinity! WTF?
Now, many of the students there, he recruited from the Catholic School where he taught during the day, so it didn't make much mind to them, they were used to religious crap in teaching. I, personally, am of a very Pagan [more of a druidic mysticism] religous outlook, and it really does tend to get on my nerves when people force their religion on others.
