Let us therefore, as many as be perfect, be thus minded: and if in any thing you be otherwise minded…
The perfect ones, among whom, by the idiom he employs, the apostle places himself, are those who have burst the fetters of intellectual and spiritual bondage; who have made some advancement in the Divine life, who are acquainted with the higher forms of truth, and are no strangers to the impulses and powers of Divine grace; who are the circumcision; who by the spirit worship God; who are conscious of union with Christ, of possessing righteousness through faith in Him, and some measure of conformity to Him, and who cherish through Him the hope of a happy resurrection. And, perhaps, if we take in the previous context the imperfect are those who have not been able so fully to rise above all confidence in the flesh; who still thought circumcision might not be wholly without value; who would scruple to count all such things dead and positive loss, but hankered after some of them; and who, in formally renouncing them secretly or unawares, clung to them, and might not distinctly comprehend the freeness, adaptation, and perfection of that righteousness which is through the faith of Christ. They could not be perfect runners, for they had not laid aside every weight.
