Hebrews 6:4

“For it is impossible for those who were once enlightened, etc..] The Syriac and Ethiopic versions render it, “baptized”; and the word is thought to be so used in (<581032>Hebrews 10:32). And indeed baptism was called very early “illumination” by the ancients, as by Justin Martyr f80, and Clemens Alexandrinus f81, because only enlightened persons were the proper subjects of it; and the word once here used seems to confirm this sense, since baptism, when rightly administered, was not repeated; but then this sense depends upon an use of a word, which it is not certain did as yet obtain; nor does the apostle take notice of baptism in a parallel place, (<581026>Hebrews 10:26,27). This gave rise…”

“We must "go on toward perfection"; for if we fall away, after having received enlightenment, it will be impossible to renew us again to repentance. for those--"in the case of those." once enlightened--once for all illuminated by the word of God taught in connection with "baptism" (to which, in Heb 6:2, as once for all done," once enlightened" here answers); compare Eph 5:26. This passage probably originated the application of the term "illumination" to baptism in subsequent times. Illumination, however, was not supposed to be the inseparable accompaniment of baptism: thus CHRYSOSTOM says, "Heretics have baptism, not illumination: they are baptized in body, but not enlightened in soul: as…”

“For it is impossible - It is needless to say that the passage here Hebrews 6:4-6, has given occasion to much controversy, and that the opinions of commentators and of the Christian world are yet greatly divided in regard to its meaning. On the one hand, it is held that the passage is not intended to describe those who are true Christians, but only those who have been awakened and enlightened, and who then fall back; and on the other it is maintained that it refers to those who are true Christians, and who then apostatize. The contending parties have been Calvinists and Arminians; each party, in general, interpreting it according to the views which are held on the question about falling from…”

“It is impossible for those who were once enlightened - With the light of the glorious love of God in Christ. And have tasted the heavenly gift - Remission of sins, sweeter than honey and the honeycomb. And been made partakers of the Holy Ghost - Of the witness and the fruit of he Spirit. Hebrews 6:5”

“6:4-8 This passage, one of the most difficult in the New Testament, gives a harsh warning about those who have left the Christian faith. Those who have fallen away from Christ and the church are like those who fell in the wilderness (3:15-19): The lack of faith shown in such apostasy results in devastating judgment (cp. 10:26-31). 6:4 In Greek, the word impossible begins the sentence for emphasis—it absolutely cannot happen (see also 6:18; 10:4; 11:6). • They were once enlightened when they “first learned about Christ” (see 10:32 and corresponding study note). • The good things of heaven might allude to the manna given from heaven (Exod 16:4, 15; Ps 78:24) as an image of spiritual blessings.”
