Wrong. Most of the Corinthians were as worldly, carnal and immature as can be yet Paul called them saints and no longer what they had been.
Keep heaping up condemnation for yourself, devil.
Where the particular believers who left Egypt under the blood, and subsequently were destroyed for their idolatry and blasphemies, also saints?
They believed did they not?
1Co 10:1 Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;
1Co 10:2 And were all baptized unto Moses in the cloud and in the sea;
1Co 10:3 And did all eat the same spiritual meat;
1Co 10:4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.
1Co 10:5 But with many of them God was not well pleased: for they were overthrown in the wilderness.
1Co 10:6 Now these things were our examples, to the intent we should not lust after evil things, as they also lusted.
1Co 10:7 Neither be ye idolaters, as were some of them; as it is written, The people sat down to eat and drink, and rose up to play.
1Co 10:8 Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand.
1Co 10:9 Neither let us tempt Christ, as some of them also tempted, and were destroyed of serpents.
1Co 10:10 Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer.
1Co 10:11 Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come.
1Co 10:12 Wherefore let him that thinketh he standeth take heed lest he fall.
Are you not aware that men call others bad names when their idols are being exposed and they will fight like hell to protect them.
Rather a silly thing to do now, when it means they love their idols more than the Lord and they are disqualified from being in the first resurrection.
How is it that you disregard the words of Paul --
Eph 4:29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
Eph 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Eph 4:31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
Eph 4:32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
