Let us discuss two of the issues:

1) Is the text Holy Scripture?

2) Was that epilogue written by Mark?

Holy Scripture is Holy Scripture when it was written. Something Jesus said to unbelievers in His day, "He that is of God heareth God's words: ye therefore hear them not, because ye are not of God." -- John 8:47.

The manuscript evidence, only a very few of [our current copies of] manuscripts omit the reading (00.2%). The evidence being the majority of early Christians accepted it as Holy Scripture.
(1) Is it Scripture ? For Catholics, it is. Regardless of who may be the author.

(2) Was it written by St Mark ? That seems harder to determine.
