You apparently do not understand the verse in question.
2 Peter 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction. (KJV)
The "Lord {δεσποτης} that bought them" in the passage is not referring to Jesus Christ {κυριος} but to God the Father.
The word used for Lord therein expresses of the power which masters have over their servants, and which God has over all mankind; and wherever this word is elsewhere used, it is spoken of God the Father, whenever applied to a divine person, as in Luke 2:29 and from the parallel text in Judges 1:4, where the Lord God denied by those men is manifestly distinguished from our Lord Jesus Christ.
By whom these persons are said to be "bought" the meaning is not that they were redeemed by the blood of Christ, for Christ is not intended. Christ is not here at all spoken of; nor is there one syllable of His dying for any persons, in any sense whatever. This is one of the more anti-Arminian verses in Scripture, not related to the atonement of Jesus Christ, so it is always bemusing that the anti-Calvinist would appeal to it as some defeater of limited atonement.
The word "bought" regards temporal mercies and deliverance, which these reprobate men enjoyed, and is used as an aggravation of their sin in denying the Lord, both by words, and by works, turning the doctrine of the grace of God into lasciviousness, being disobedient and reprobate to every good work. See Deuteronomy 32:6 from where this phrase is borrowed, and to which it manifestly refers: "do ye thus requite the Lord, O foolish people and unwise! is not he thy Father that hath bought thee? hath he not made thee, and established thee?"
See also 2 Peter 2:12 and compare with Deuteronomy 32:5. Note also that the persons Peter writes to were Jews, who were called the people the Lord had redeemed and purchased, Exodus 15:13 and so were the first false teachers that rose up among them; and therefore this phrase is very applicable to them.
In other words,
"Those Jews who reject Christ are rejecting the God of their Fathers, who ransomed them from bondage in Egypt".
Bryson's anti-Calvinist crusade with CCA is well-known. Perhaps you and he should actually read the sermon from wherein this quote is liberally lifted:
Sermon VI - 2 Tim. 2:19
I suspect not a few who cavil about Calvinism have even read the man's sermons, nor fully apprised themselves of his full corpus of works. No, they simply prefer to quote mine from them, never doing their due diligence to take every word captive for the glory of God.
Like you, Bryson's assumption that 2 Peter 2:1 is speaking about the atonement of Our Lord Jesus Christ is nonsense and only illustrates the often superficiality of the anti-Calvinist.
Given what you have written at this site, the bravado present in your post above serves to bolster the overwhelming opinion that you really do not know what you are talking about on any matters of Scripture. The passage in question speaks directly to your current state of affairs, sir. Take heed.
