Jesus’ preaching ministry was not his kingdom as you say, confusing the two:
“Old Testament prophecies on Christ's ministry the Church talk of it as perpetual and incorruptible as a whole
Daniel 7:13-14: “. . . behold, with the clouds of heaven there came one like a son of man , and he and his kingdom one that shall not be destroyed”
You say:
“The history of actions of some men in orthodoxy does not affect the basic faith which is of Christ Jesus as He spoke...”
The corrupt and murderous Pharisees said they had the “orthodox” faith and they had their “place” and yet despite having ritual and the Bible and long history that nation was rejected by Christ. At Matthew 21:43 Jesus said the kingdom would be taken away from them and given to a nation bearing it's fruits.
And it was because of those leaders who were guilty of murder and hypocrisy their “house” was abandoned and those who would follow Christ had to abandon it too or perish in 70 a.d.
Now that the crop is ripe who are weeds is quite evident as one scandal after another come to fruition.
The various heresies that we see and have seen, are the weeds that died quickly even though they seemed so strong at one point in time -- Arianism, Manichaenism, Gnosticism, etc. etc.
Just in the same way we see both the heresies that have sprung up in the past 100-150 years (Mormonism, Adventism, Jehovah's Witnesses, Christian Scientists) as dying out, and even the other, incomplete messages of faith are dying out as they are not strong enough to stand up to the light
Now that the crop is ripe who are weeds is quite evident as one scandal after another come to fruition. -- yes, this is visible in the various groups outside the Apostolic Church -- they are roiled with one scandal of their dogma after another
The Apostolic Church itself may have faulty men in laity and clergy, but the dogma is scandal-free as it is the dogma of the Christ Himself.
THAT is the big difference between the One Holy Apostolic Church (Catholic, Orthodox, Oriental) and both the incomplete groups and the heresies -- the incompletes and the heresies die out rapidly due to scandals of men, while for the Church that Christ founded, it has remained through 2000 years INSPITE of faulty men.
These groups that lie outside the Apostolic Church are groups of men, formed by men and dependent on just men. hence they fall when the many scandals and faults of men appear
In contrast in the Apostolic Church, if we have a sin filled priest (and hey, they are human after all), that matters not. If they are criminals boot them in prison, that doesn't affect our Church. If they can't preach, that matters not.
Because we look beyond this human vessel and focus on Christ in the Eucharist
During our Holy Prayer to God, what do we have?
oh, my friend in Christ, we are blessed to have experienced this -- and where does the minister figure in all of this? He is just a tool, a means. God uses splendid tools or weak ones, but they are just tools
What is at the centre of our Churches? Not like in others, the pulpit, glorifying the preacher, but in Our Church the center-piece is the altar with the Eucharist, the Bible and the Cross, remembering us of Our Risen Lord, His sacrifice and His Word
