Here's the context. Don't mind the grammar since its just the first draft, unless the grammar is 'that' bad.

As requested I haven't addressed grammar too much. The parts I'm suggesting you omit are in bold and any suggested revisions are underlined. It's often difficult to know when to stop with accumulated research material..I think the thing to keep in mind is that you are not teaching history, you are setting the scene. This is only a quick adjustment I might make if it were my own.
Nuns shielded their faces with their long-sleeved gowns as they came across the soldiers. It was forbidden for them to reveal their visage identities. Around five-hundred years ago, practitioners of the Old Covenant were all males. Acolytes that trained would soon become priests, or church guardians, ministers who taught at schools—teaching the fundamentals of their faith. Some would become missionaries to travel in different grounds to spread the word and teachings of Ishnual—the High God, the Prime Genesis, Historian, Carpenter and Maker of Paths, the Lord of All that Has to Come. Ishnual had received many different names and titles, as the Old Covenant was widely accepted in the West and in the South, in the East, religions there were different yet were based on the influences of Ishnual, and parts of the North had small societies worshipping his holiness.
However, sometime around those years back,But then a single woman, Alyssa Tennet of Meddos, was conceived to be the First Lady of Saints, because of her compassion of others, and having the her unique ability to heal every wounds even those that would scar deep and fatal. She was first regarded to be a witch, or a demon-possessed, or the Interloper in disguised. But then, wiser priests came to acknowledge Alyssa’s talent as a gift, a blessing from the High God, Ishnual, and that, she be allowed to serve in church of the Old Covenant if she pleased to. And she did as she healed the sick.
Many months later, When other women claimed to have possessed the same gifts. Numerous of them failed to produce evidences while some had long disappeared when asked for proof, and a few had used a magician’s trick in the Arts of Skin Tapping but was discovered quickly. And from then on, the First Lady had filed a request to the Cardinal that women too, must be allowed to serve their god in the same way as men ought to do.
It wasn’t until three years had passed, when the Council of the Covenant finally agreed upon the First Lady’s request and women wishing to enter the threshold of the church as servants were to be virgins and never look at the faces of men for fear of drawing upon desire and lust, either in themselves or in the men upon whom they looked. Though, there were conditions, strict conditions that women must follow if they wished to enter the church’s thresholds as a servant. First of the conditions was obvious, the woman must be a virgin and without a husband whether in the present or in the past. The second was never to look at the faces of men, for physical features may draw upon desire and lust, nor shall the woman allow her face to be seen by men, for it too, may draw upon desire and lust. After all, children of Ishnual, are human.
Around 2852AC, the practices and traditions of the Old Covenant have evolved, because of nuns disappearing every now and then. And it was discovered that, nuns and acolytes, even some priests, have difficulty in staying apart from each other. Which had then caused the nuns’ flee as the only solution for their shame. This had caused a separation of houses of the religion. House Jesmond for the acolytes, and House Tennet for the nuns. And one hundred years after that, it was enforced by the Hand of Three, that no child older than five may practice in becoming a servant, nun or acolyte, to discipline them while young.
The same discipline could not be said in is not practiced in thiis day’s religious era. Women were are allowed to enter the churches as servants regardless of their age and history. It was by the words of the 31st Pope of the Holy Covenant of Ishnual that ‘nothing stays forever as life moves on’ believing that no matter how sinful or evil one was once, as long as they accept Ishnual with all their heart and soul, Ishnual would grant them forgiveness’. Many have protested even faiths of the Nich’Tella Crid had come to argue whether or not was this decision to be an act of heresy or a ‘change’ as the pope had said. The 31st Pope, Que’Elazar III, had only nodded and smiled saying, ‘that is not for me to answer, it is our god’s.’ And as time passed, nothing had seemed to change, until recently, when people began to take advantage of the sudden change of tradition, when beggars began to enter churches proclaiming that they wish to become servants of Ishnual, and then came the whores when whoring became illegal. Servants of their faith were under protection of the Old Covenant, therefore, voiding all crimes and sin they had committed, unless the church had decided to relinquish them—however that was controversial.
And now, what had remained remains of the holiness of the Old Covenant? Little. Hypocrites and heretics continue to fill the churches of such immorality, and only a few, mostly remote, regions where the Old Covenant had established had remained sacred.
