***No, our faith is based on the Bible and Traditions passed on for the past 2000 years, just as the Bible teaches.***
The Bible says it contains everything we need to know to be saved and to live a life pleasing to God.
***Only Mary needed to be sinless.***
Why did Mary need to be sinless?
The Bible also says that there were many other things that happened that were not written in the Bible. These things were passed onto us by the disciples and their successors. Matthew tells you to go to the church to solve issues such as this. Well, the church settled this a long time ago. I will listen to the church.
