Doctrinal Divorce

Doctrinal triage is doctrine divorce. It’s a severing of doctrine by man when in reality all doctrine is married not only to each other, but to God’s very nature. His doctrine is true reality and reveals His mind (1Cor. 2:16).

It is interesting that Scripture doesn't allow for giving false teachers/ apostates a platform,nor says they have some truth that we can learn from. It states just the opposite. The claim of "who has perfect doctrine" is destroyed in this passage, as is the anti-Lordship salvation view:

On the qualifications of elders [caps, my emphasis]:

Tit 1:9 holding fast the faithful word which is in accordance with the teaching, so that he will be able both to exhort in sound doctrine and to refute those who contradict.
Tit 1:10 For there are many REBELLIOUS men, empty talkers and deceivers, especially those of the circumcision,
Tit 1:11 who MUST BE SILENCED because they are upsetting whole families, teaching things they should not teach for the sake of sordid gain.
Tit 1:12 One of themselves, a prophet of their own, said, "Cretans are always liars, evil beasts, lazy gluttons."
Tit 1:13 This testimony is true. For this reason REPROVE THEM SEVERELY so that they may be sound in the faith,
Tit 1:14 not paying attention to Jewish myths and commandments of men who turn away from the truth.
Tit 1:15 To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure, but both their mind and their conscience are defiled.
Tit 1:16 They profess to know God, but by their deeds they deny Him, being detestable and disobedient and WORTHLESS for any good deed.

Indeed, myths and dogmatic teachings of men weren't harmless things they could hold to along with truth. Additionally a godly life is in direct correlation to sound doctrine (v. 9-16). Charismaticism is demonic and earthly, it is gnostic and fleshly. So to accept it as valid is to violate Titus 1.

Doctrinal fidelity in all doctrine proves one's fidelity to Christ Jesus.

2Co 11:3 But I am afraid that, as the serpent deceived Eve by his craftiness, your minds will be led astray from the simplicity and purity of devotion to Christ.
2Co 11:4 For if one comes and preaches another Jesus whom we have not preached, or you receive a different spirit which you have not received, or a different gospel which you have not accepted, you bear this beautifully.

Deu 13:3  you shall not listen to the words of that prophet or that dreamer of dreams; for the LORD your God is testing you to find out if you love the LORD your God with all your heart and with all your soul. 4  "You shall follow the LORD your God and fear Him; and you shall keep His commandments, listen to His voice, serve Him, and cling to Him. 

Doctrinal triage also divorces doctrine from practice (sanctification), so the practice of some sin is ok (as shown above) like fellowship with Belial or darkness via gnostics or false teachers even (2 Cor. 6). 

When people use a doctrinal triage, they are divorcing sanctification from salvation, etc, which rejects the whole point of salvation which is that: we are God’s handiwork (Eph. 2:8-10), created for the end of our salvation (Eph. 1:3-4,10-12; 1 Peter 2:12; 4:10; Titus 2:14; 2Thes 1:11-2) which is for His full glory, magnifying His grace in full praise for these attributes of His, according to His decree, purpose, plane, and will (1:4,9-11;2:6-7) and power (Eph. 1:19). We also are saved to the end of salvation for an inheritance (Eph. 1:1,4,18; 5:5; Col. 1:12, 3:24; Heb. 9:15). All of this demonstrates God’s power and Christ’s glory over all (Eph. 1:20-23).

1Th 4:7 For God has not called us for the purpose of impurity, but in sanctification. 8 So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
