Catholics are not obligated to believe the revelations of saints (such as St. Bridget) …revelations which are in addition to sacred scripture and Catholic teaching of the Magesterium.
Here are just two of the many scriptures which speaks on this subject.
“Now are we the children of God, and it does not yet appear what we shall be, but we know that when He shall appear, we shall be like Him, for we shall see Him as He is, and everyone who has this hope in themselves, purifies themselves, even as He is pure.”
**"Our citizenship is in heaven, from whence also we look for our Lord Jesus Christ, who shall **transform ****(metamorphize) our lowly bodies like unto his glorious body, according to the power whereby he is able to subdue all things unto himself."
Catechism of Perseverance, Second Course, Chapter XXII:
Q. What are the qualities of the body glorious?
A. The bodies of the saints after resurrection will have four principal qualities; impassibility, by which they will be incapable of feeling any inconvenience or suffering; brightness, which will render them more brilliant than the sun, and which will be greater or less, in proportion to the merit of the saint; agility, which will free the body from the weight which bears it down, and will permit the soul to carry the body whithersoever it chooses with facility and speed; lastly, subtlety, which will render the body entirely subject to the soul.
