OK,
@St. SteVen, I pondered this on my morning walk/run and here's my contribution. THEN IT'S NAP TIME. I'll be 74 next week, so I'm definitely a "mature person who is a Christian" even if I'm not a "mature Christian" (although my wife and most who know me might even challenge the mature person part).
______________________________________
I'm tempted to paraphrase what a Supreme Court Justice said about obscenity: "I can't define Christian maturity, but I know it when I see it." But even that isn't really true. Perhaps: "If you think you can define Christian maturity, you probably aren't a mature Christian." Worse yet: "If you think you
are a mature Christian, you surely aren't."
I've known Christians who absolutely radiated the peace, joy, love, contentment and other fruits of the Spirit we'd all love to have. But wait, I've known non-Christians who radiated the same things. Hmmm. I suppose a Christian who radiated the opposite would have difficulty getting anyone to accept him as a mature Christian (take the hint, Bibliolators!

).
I don't think it has much to do with where one falls on the wide spectrum of Christian belief. I'm confident there are mature Christians in every branch of the faith.
Whether we're talking about Christians or non-Christians, we're all the product of genetics, childhood influences and other factors beyond our control. My next-door neighbor, now deceased, was an uneducated Alabama farm boy and retired railroader who had been the town drunk, whoremonger, wife-beater and general hell-raiser. He was widely known and detested. I
loved the old fart – we became like father (him) and son. He was still a hair-trigger handful, but he truly loved God and was doing the best he could. He was a mature Christian in comparison to what he had once been, that's for sure.
I probably should address whether I think I'm a mature Christian. My honest answer would be, "In a way, but not really." I'm a "scholastically mature" Christian – I've surely studied as much philosophy, theology, apologetics and related subjects as anyone this side of a cloistered monk. But that's just who I am – scholastic by nature. A deep understanding of the issues and doctrines may have
something to do with being a mature Christian, I think – but probably not a great deal.
Am I a faithful churchgoer and gospel proclaimer? Uh,
no. Tell my neighbors for the past 27 years that O'Darby is a serious Christian and they're going to respond, "O'Darby is a Christian? We had no idea. We know he has a lot of cats."
Have I made the best, in the Christian sense, of the talents with which God has blessed me? Uh,
no. I am literally
staggered by what some Christians do, and suffer, for their faith. At one place where I worked, I learned that a Christian guy (who made far less than I did) and his wife had made six trips to Ukraine, and endured all the absurd red tape six different times, in order to adopt six Ukrainian orphans and raise them in their modest home in our little town. He never even spoke about it – I learned it from someone else. Or listen to the "Voice of the Martyrs" radio program if you want to be humbled. Suffice it to say, I spend a fair portion of my prayer time apologizing to God for not doing a whole lot (but don't overlook all those feral cats I'm feeding, Jesus!).
I'm pretty kind and certainly very generous – money means close to nothing to me – but not a "good Christian" in the way most people would define it. I'm not expecting any gold crowns in heaven. I will say that, over the decades, I
have seen a fundamental transformation in Who I Am without any conscious effort on my part, which is what convinces me there is some reality to the indwelling of the Holy Spirit.
I would probably define a mature Christian as one who is:
- secure in his convictions and comfortable with his doubts and questions;
- nondogmatic about what others should or must believe;
- accepting of the fact that God is an eternal transcendent Other whose ways must remain mysterious to His creatures;
- accepting of the fact that Christianity is not a tidy, connect-the-dots religion but a faith and a way of relating to God that must be experienced and lived;
- accepting of the fact that the Body of Christ includes an incredible diversity of personalities, understandings and talents and that this is what God intended;
- able to see the humor and even the absurdity in all this;
- accepting of his own humanity and the inevitable stumbling, fumbling and failure;
- regularly engaged in prayer and communion with a primary focus on the needs of others and his own shortcomings and failures;
- living in a near-constant state of gratitude to God for His creation and the opportunity to be a part of it; and
- at least making his best effort to lead a life pleasing to God in whatever circumstances he finds himself, even though his life may pale in comparison to those of the saints or an ideal Christian life.
By this standard, I delude myself into believing that I'm at least a somewhat mature Christian, albeit one whose Christian walk falls far short of the ideal. But it's also probably why Bible-thumpers tend to see me as "Not a Christian at all."
Nap time. :Zzzzz: This could last a week or more.
