I'll take it a step further and say that the Bible says the EXACT OPPOSITE:
[30] Many other signs also did Jesus in the sight of his disciples, which are not written in this book.[31] But these are written, that you may believe that Jesus is the Christ, the Son of God: and that believing, you may have life in his name.
-- John 20:31-31___________________________________________________________
[24] This is that disciple who giveth testimony of these things, and hath written these things; and we know that his testimony is true. [25] But there are also many other things which Jesus did; which, if they were written every one, the world itself, I think, would not be able to contain the books that should be written.
-- John 21:24-25
And keep in mind that the Immaculate Conception and Assumption of the Blessed Mother are things that JESUS DID, not Mary.
the Immaculate Conception and Assumption of the Blessed Mother are things that JESUS DID, not Mary.God did all of this, Mary's Savior, Our Lord, did this.
There's a reason John didn't tell us the other signs that Jesus performed...And that's because they were nothing that we needed to know for our salvation...
If there was an Immaculate Conception and Assumption of Mary, Jesus would have told us...And since He didn't, your religion is just making it up...
