Are you okay bro? Are you stressed lately? Calm down first off.
Let's assume parts of the Church at times did whore it up with the state. She's still my mother. I am the worst of all whores, and she is still righteous in my eyes. St. Constantine, he is still righteous in my eyes, and I wish I could be a tenth of the man he is.
Christ protected the whore from the Pharisees. He did not tell the Pharisees "He who has lesser sins may cast the first stone." He said, "He who is WITHOUT sin may cast the first stone." If I did even one tiny sin in my life, let's say a white lie like telling someone "your cake tastes delicious" when in fact it was terrible, then I do not deserve to throw stones at my mother Church or at St. Constantine for that matter. I condemn his actions, and I would show disapproval of all the wrongs he did, but I will not condemn his whole person.
Origen, the man I love so much, may in fact have helped Arianism grow at the time unfortunately. But I do not want to condemn his person either. He is too precious in my eyes, and too righteous beyond any compare for me, giving birth to great holy men.
Many priests in the past may have owned slaves. We should condemn that with no exception, but their persons remain untouchable. Condemn perhaps even some of the canons that may have condoned slavery in some way. But at the same time, we can recognize that the Scriptures make it clear, perhaps not necessarily directly condemning slavery, but as if slavery didn't exist. In fact, if anything, the Church rather than teaching we are all men born free, the Church teaches we are all born slaves. The ecclesiological structure of the Church, I just learned from Fr. Thomas Hopko, terms like "episkopos", "hegumenous", "diaconos" all were positions in slave orders in households, with the head slave as "episkopos" entrusted with overseeing all the other slaves in a household. The Church reminds us in her ecclesiology that we are slaves to Christ, and only through slavery to Christ are we truly made free in spirit. It is why this American individualism never existed in the thought of the Church. It is also why the Church prohibited from outrightly using religion as a means to enforce masters to free slaves. The spiritual structure of Christianity was using a much more humble approach to destroy the status quo.
Let's face it! I agree with you that ever since Christianity was legalized, slowly the Church lost track of its spirituality in being slaves to Christ, and instead were turned to masters over dioceses. Perhaps, we went a few steps backwards due to our legal standards. But we also see monasticism grew during this time, as a recognition of and rebellion against "sham Christians". And we see many holy men who stood against St. Constantine and his subsequent successors in imperial authority, like St. Athanasius, St. Gregory Nazienzen, St. Gregory of Nyssa, St. John Chrysostom, all of whom were spiritual and theological giants and define a huge chunk if not most of our spiritual Orthodoxy until today.
Popes Callistus I and Pius I as well as St. Patrick, St. Onesimus to name a few, all were bishops and all were slaves. And Christianity taught the Roman world that slaves were to be treated as humans, not as property as were once practiced by pagans. The Church did undermine the order of slavery even if it didn't abolish it. It even gets pretty clear when St. Paul names slave-traders along with fornicators, homosexuals, and liars (1 Timothy 1:10). Thus, the teaching is there, and the Church faith is implied, even if it wasn't made manifest until recently. You have to forgive the ignorance of the Church fathers in the past. Things happen to occur by continued revelation, not in one fell-swoop. Revelations of truth had to happen in their own times, and we have to at least acknowledge that while some in the Church may have done things that were displeasing, overall, the Church has been ahead of the curve at all times. The services and sacrifices that the Church partook in were incomparable to what the rest of the world was doing, whether or not there were mistakes made. The Church always transcended the world, not equal to the world, but not far beyond anything the world could fathom, that the world may progress with the Church little by little. Services to the poor, to orphans (making orphanages and adoptions were unheard of!!!), to widows, to the lepers and other sick people (even a sacrament was made for them and hospitals were made by Christians), raising the status of women more than other cultures did, raising the status of slaves as equal to masters even if they still continued to be slaves, they turned many aboriginal communities to thriving, educated, and tolerant communities.
Consider this quote:
To this I may compare the case of Theology except that it proceeds the reverse way. For in the case by which I have illustrated it the change is made by successive subtractions; whereas here perfection is reached by additions. For the matter stands thus. The Old Testament proclaimed the Father openly, and the Son more obscurely. The New manifested the Son, and suggested the Deity of the Spirit. Now the Spirit Himself dwells among us, and supplies us with a clearer demonstration of Himself. For it was not safe, when the Godhead of the Father was not yet acknowledged, plainly to proclaim the Son; nor when that of the Son was not yet received to burden us further (if I may use so bold an expression) with the Holy Ghost; lest perhaps people might, like men loaded with food beyond their strength, and presenting eyes as yet too weak to bear it to the sun's light, risk the loss even of that which was within the reach of their powers; but that by gradual additions, and, as David says, Goings up, and advances and progress from glory to glory, the Light of the Trinity might shine upon the more illuminated. For this reason it was, I think, that He gradually came to dwell in the Disciples, measuring Himself out to them according to their capacity to receive Him, at the beginning of the Gospel, after the Passion, after the Ascension, making perfect their powers, being breathed upon them, and appearing in fiery tongues. And indeed it is little by little that He is declared by Jesus, as you will learn for yourself if you will read more carefully. I will ask the Father, He says, and He will send you another Comforter, even the spirit of Truth. This He said that He might not seem to be a rival God, or to make His discourses to them by another authority. Again, He shall send Him, but it is in My Name. He leaves out the I will ask, but He keeps the Shall send, then again, I will send,—His own dignity. Then shall come, the authority of the Spirit.
You see lights breaking upon us, gradually; and the order of Theology, which it is better for us to keep, neither proclaiming things too suddenly, nor yet keeping them hidden to the end. For the former course would be unscientific, the latter atheistical; and the former would be calculated to startle outsiders, the latter to alienate our own people. I will add another point to what I have said; one which may readily have come into the mind of some others, but which I think a fruit of my own thought. Our Saviour had some things which, He said, could not be borne at that time by His disciples (though they were filled with many teachings), perhaps for the reasons I have mentioned; and therefore they were hidden. And again He said that all things should be taught us by the Spirit when He should come to dwell amongst us. Of these things one, I take it, was the Deity of the Spirit Himself, made clear later on when such knowledge should be seasonable and capable of being received after our Saviour's restoration, when it would no longer be received with incredulity because of its marvellous character. For what greater thing than this did either He promise, or the Spirit teach. If indeed anything is to be considered great and worthy of the Majesty of God, which was either promised or taught.
--St. Gregory the Theologian, Oration 31.26-27 (aka the Fifth Theological Oration)
Therefore, there are many things hidden within the spirituality and theology of the Church that has to be revealed in its own time. We can't suddenly receive all teachings. The Church is not a static Church that has a catechism from the day of the Pentecost. She grows "from glory to glory" (2 Corinthians 3:8), and reveals things in all humility and in due time.
Therefore, we also must be humble in judging the past, and not use our anachronistic judgments to emotionally find ourselves disagreeable with the Church at all times. Cultivate within yourself the fruits of the Spirit, and the first four is quite telling: love, joy, peace, and patience. Love the Church even in her dark times. Be joyous in your communion within the Church, for through Her, Christ is perfected in YOU. Keep your peace at all times, and never lose your peace even in times when you are troubled. Love, joy, and peace in tribulations will give you clarity of mind, and with it culminates all in patience, or a better word: long-suffering. Because when we jump to judgments, we become disgruntled and easily discouraged. First preserve your love, peace, joy, and patience...then ask, "why did the Church do this? No, this is not right. We know NOW as the Church may have not been able to understand before that slavery is wrong completely, and should be done away with. But I still love her saints, and I am still ever more at joy and peace in being with Christ, who gives me more than I deserve."
We know now, hidden within the Pauline verses in the Scriptures, within the ecclesiological structure of the Church, within the examples of the saints and Church fathers that inducing slavery from our own is wrong, and that we are taught no matter what position we hold, even if emperor of the world, we are all still slaves to Christ and equally human. This central Christian theological dogma has always been taught, but only recently realized. Forgive the past, and look forward to upcoming glory in Christ through His most glorious and worthy Church. In fact, while there were white Christian bigots, there were also white Christian abolitionists that through sound theology lead the liberation movement for black people in the US. This all the more should prove within the Scriptures and Church spirituality lie a revelation of truth that always was there, but may have been unrealized until now, even among those Christians outside the Church in the US. So don't just look at how the Church may have got things wrong, but also look at the vast history of how the Church got things more right than ever!
