Christian Maturity -- Ephesians Style

until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, (Ephesians 4:13, ESV)

The verse quoted above has to be explained a bit because I am quoting it out context. First, Paul is addressing the church as a body and the unity of the Church is Paul's main theme in Ephesians. O'Brien puts it this way in his commentary on Ephesians.

‘to the mature man’. This destination to which all believers are headed is understood as a corporate entity: it is not described in individual terms, but refers to the totality of believers as the body of Christ.

Mature man is an unusual term. Brooks Simpson pointed this out in his sermon a few weeks ago. We are corporately as a body growing into a mature man. Our unity is not an option; it is foreordained. O'Brien further explains what the term means.

The phrase ‘mature man’ is somewhat unusual since the term for an adult male or full grown man is used, rather than the generic word for man or human. The adjective has the sense of ‘mature’ (cf. Cor. 2:6, 14:20; Heb. 5:14) rather than ‘perfect’, and focusses on the mature adult person in contrast with the infants of v. 14.

Here are two quotes about the goal specified by Ephesians 4:13. We have an impossibly high standard to meet that needs to be realized step by step in the present age with the help of the Holy Spirit.

The church is already the fullness of Christ (1:23; cf. 4:10). There is thus a realized dimension to its existence. But the future element is still present: the apostle has prayed that the readers might be ‘filled up to all the fullness of God’ (3:19); now in the immediate context the goal to be reached is mature manhood, and this is defined by the fullness of Christ. The maturity of this growth is measured by nothing less than Christ’s full stature. ‘The glorified Christ provides the standard at which his people are to aim: the corporate Christ cannot be content to fall short of the perfection of the personal Christ.” (O’Brien, p. 308)

When the goal is ultimately reached, and the body of Christ has grown up sufficiently to match the Head Himself, then will be seen that full-grown Man which is Christ together with His members. That spectacle will not fully appear until the day when they are glorified together with Him; but the expectation of that day will act a powerful incentive to spiritual development in the present time.
