"I understand that catholics do not base their beliefs on scripture, but if they are confident in this aspect, neither should they attempt word games to make scripture support their already held doctrine."
On the contrary, Catholics believe that Holy Scripture is the very soul of sacred theology. But Scripture itself tells us to hold fast to all the tradtions that we have received from the Apostles.
If by "word games" you are referring to typology, I think you will find we have a very good precedent in the authors of the NT, and the semitic tradition generally.
"We" don't!
