He said "aid the faith." Reinforcing a Catholic ruler's retinue at max speed means a stronger Catholic ruler, which certainly seems like "aiding the faith" to me...
and my team of crack lawyers, who just recently helped me convince a fellow ruler that I did him a favor after executing three of his sons I'd captured in battle while castrating the ruler himself, because with one imbecile son and no way to produce new heirs, his kingdom now won't be ravaged by gavelkind. (They're great lawyers.)
It pays to hire Massingbird & Co.
I remember Massingbird's most famous case: the Case of the Bloody Knife. A man was found next to a murdered body. He had the knife in his hand. 13 witnesses had seen him stab the victim. And when the police arrived, he said "I'm glad I killed the bastard." Massingbird not only got him off; he got him knighted in the New Year's Honours List. And the relatives of the victim had to pay to wash the blood out of his jacket!
