Oh... this made me laugh.
Now for the breakdown: (PLEASE NOTE: I referenced many of my replies to the video with bible verses. No offense is intended, they are simply there for reference purposes.)
"Judas is another name for Jesus"
Jesus' Hebrew name was most likely "Yeshua" which is translated as "Joshua". The "Judas" in the song is referring to Judas Iscariot, a disciple of Jesus, who betrayed him.
(Mat 10:4 Simon the Cananaean, and Judas Iscariot, who betrayed him.)
"Lady Gaga is a part of the Illuminati"
If I may borrow from Yahtzee, "Pants on head retarded".
"Sex is a major sin"
The bible advocates that marriage is a good and healthy thing, and married people (typically) have sex so...
(1Co 7:28 But if you do marry, you have not sinned)
"If you listened to this song, you are probably going to hell"
Because she made a video about the content of the song, by her own logic she is going to hell.
"I need to be saved again."
According to most Christian doctrine, this statement is rather outlandish. Generally, theology states that once you are saved, you cannot lose your salvation. This belief is based largely on the verse below.
(Rom 8:38-39 For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, (39) nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.)
"I think that you are all beyond hope"
By that logic, what is the point in making the video?
(Mat 28:18-20 And Jesus came and said to them, "All authority in heaven and on earth has been given to me. (19) Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, (20) teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.")
Lady Gaga is an exhibitionist. Just ignore her and she'll go away.
