As I have grown in Jesus, as I have undergone the process of “sanctification”, as I have “put off the old man and put on the new”, it can be said I have been being “formed in Christ”. Richard Foster coined the phrase “Spiritual Formation” in his book “The Celebration of Discipline” (1978 HarperSanFrancisco) which, as memory serves, was coopted from the apostle Paul who plead with the Galatians against legalism:
Have I therefore become your enemy because I tell you the truth? They zealously court you, but for no good; yes, they want to exclude you, that you may be zealous for them. But it is good to be zealous in a good thing always, and not only when I am present with you. My little children, for whom I labor in birth again until Christ is formed in you, I would like to be present with you now and to change my tone; for I have doubts about you. (Galatians 4:16-20)
Foster writes from his Quaker upbringing, and from a pastoral perspective, as he encourages believers to embrace a simple, and disciplined lifestyle in celebration of being formed into Jesus. The same message as we read over and over in the New Testament epistles. Other well-known writers have since picked up the “Spiritual Formation” batton, and are continuing the race by adding in their own perspectives. I first read Foster’s book in the mid 90’s and I found it to be very helpful encouragement.
I hear testimonies from scoffers, contenders who eschew any Christian “discipline” as “faddish”, “legalistic”, or as “seeking an ecstatic experience”, or something else. While some surely may erroneously engage in various activities for those kinds of reasons, I did not find any of that kind of encouragement in Mr. Fosters book.
To me, Spiritual Formation is synonymous with what modern Christians call sanctification, meaning, the process of growing into Christlikeness. Spiritual formation is a common path on which all believers, who are “born from above” travel, although the scenery along the path may vary from saint to saint. Celebrating a disciplined, and simple lifestyle which encourages maturity and fosters selfless compassion is a universal admonishment for The Church of Christ.
Being Formed with you
