How did the Early Church interpret Hebrews 6:4-6, Hebrews 10:26-31, 2 Peter 2:20-22, and other similar passages?

> [Hebrews 6:4-6 NASB] 4 **For it is impossible, in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit**, 5 **and have tasted the good word of God and the powers of the age to come**, 6 **and then have fallen away**, to restore them again to repentance, since they again crucify to themselves the Son of God and put Him to open shame. > [Hebrews 10:26-31 NASB] 26 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a terrifying expectation of judgment and the fury of a fire which will consume the adversaries. 28 Anyone who has ignored the Law of Moses is put to death without mercy on the testimony of two or three witnesses. 29 How much more severe punishment do you think he will deserve who has trampled underfoot the Son of God, **and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace**? 30 For we know Him who said, “Vengeance is Mine, I will repay.” And again, “The Lord will judge His people.” 31 It is a terrifying thing to fall into the hands of the living God. > [2 Peter 2:20-22 NASB] 20 For if, **after they have escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and are overcome, the last state has become worse for them than the first**. 21 **For it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment handed on to them**. 22 It has happened to them according to the true proverb, “A dog returns to its own vomit,” and, “A sow, after washing, returns to wallowing in the mire.” And other similar passages: > [Galatians 5:1-5 NASB] It was for freedom that Christ set us free; therefore **keep standing firm and do not be subject again to a yoke of slavery**. 2 Look! I, Paul, tell you that if you have yourselves circumcised, Christ will be of no benefit to you. 3 And I testify again to every man who has himself circumcised, that he is obligated to keep the whole Law. 4 **You have been severed from Christ**, you who are seeking to be justified by the Law; **you have fallen from grace**. 5 For we, through the Spirit, by faith, are waiting for the hope of righteousness. > [Luke 8:13 NASB] Those on the rocky soil are the ones who, when they hear, receive the word with joy; and yet these do not have a firm root; **they believe for a while**, **and in a time of temptation they fall away**. > [Matthew 13:20-21 NASB] 20 The one sown with seed on the rocky places, this is the one who hears the word and immediately receives it with joy; 21 yet he has no firm root in himself, **but is only temporary**, and when affliction or persecution occurs because of the word, **immediately he falls away**. > [John 15:5-6 NASB] 5 I am the vine, you are the branches; the one who remains in Me, and I in him bears much fruit, for apart from Me you can do nothing. 6 **If anyone does not remain in Me, he is thrown away like a branch and dries up; and they gather them and throw them into the fire, and they are burned**. > [Romans 11:18-22 NASB] 18 do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you. 19 You will say then, “Branches were broken off so that I might be grafted in.” 20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; 21 for if God did not spare the natural branches, He will not spare you, either. 22 See then the kindness and severity of God: **to those who fell, severity, but to you, God’s kindness, if you continue in His kindness**; **for otherwise you too will be cut off**. > [1 Corinthians 9:24-27] 24 Do you not know that those who run in a race all run, but only one receives the prize? **Run in such a way that you may win**. 25 Everyone who competes in the games exercises self-control in all things. So they do it to obtain a perishable wreath, but we an imperishable. 26 Therefore I run in such a way as not to run aimlessly; I box in such a way, as to avoid hitting air; 27 **but I strictly discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified**. > [Revelation 3:5 NASB] The **one who overcomes** will be clothed the same way, in white garments; and **I will not erase his name from the book of life**, and I will confess his name before My Father and before His angels. > [Revelations 22:19 NASB] and if anyone takes away from the words of the book of this prophecy, **God will take away his part from the tree of life and from the holy city**, which are written in this book.
