Hebrews 6:4-6

New Catholic Bible

^4 [a]For when people have once been enlightened and have experienced the heavenly gift, and have shared in the Holy Spirit, ⁵ and have tasted the goodness of the word of God and the powers of the age to come, ⁶ and then in spite of all this have fallen away, it is impossible to restore them again to repentance. For they are crucifying the Son of God for themselves once again and are holding him up to contempt.
