I've noticed that.
>>I don’t know why you are hanging on this one line about oracles.<<
I don't doubt that for a minute.
>>What does the Church teach the Apostles didn’t?<<
Please show where the apostles taught the assumption of Mary or the need to believe that to attain salvation. How about praying to those who have passed from this life?
>>It seems Our Lord, in doing many other signs likely talked<<
To the human mind many things seem likely"
>>Again, it was teaching of the Apostles, not recorded in the Bible, but recorded in the works of disciples of the Apostles, along with the Scriptures that were taught to the earliest Christians.<<
And 6 of the 7 churches addressed in Revelation had already gone astray. Not good odds.
One doesn’t need to believe in the Assumption to attain salvation. Jesus, through His Passion, Death, and Resurrection attained our salvation, once and for all. No person can earn salvation, nor merits it. It is freely given by God.
The Apostles likely wouldn’t have taught the Assumption, as many had been martyred prior to her death. Because an exact date is not recorded, we can’t know for sure, on that point.
To believe that Jesus didn’t speak to the Apostles about His teaching is just absurd.
I don’t worry, as Jesus told the Apostles the gates of Hell would not prevail against His Church, built upon Peter.
