Anything apart from faith in Christ will not get you into Heaven.
If the catholic is relying upon all of the "Mary" stuff they've been taught to get them into Heaven, forgive their sins, etc, they are going to be sadly disappointed.
As we know....Jesus said, "I am the way, the truth, the life; NO ONE comes to the Father but through Me." John 14:6
The Greek behind this statement is emphatic.
In essence, Jesus is saying, compared to Me there is no other way to Heaven.
Not through Mary.
Not through Paul.
Not through mom or dad.
Not through Apollo.
Not through Zeus.
Not through Mohammad.
Not through Buddha.
It is only through Christ and Christ alone do we gain Heaven.

Only through Yeshua can Torah be written on your heart.
Only with Torah written on your heart can you arrive at the wedding feast with your garment, white as snow.
