Problem: Certain technological inventions of the period whether of Arab or Chinese origin, or unique European innovations were to have great influence on political and social developments, in particular gunpowder, the printing press and the compass. The introduction of gunpowder to the field of battle affected not only military organisation, but helped advance the nation state. Gutenberg's movable type printing press made possible not only the Reformation, but also a dissemination of knowledge that would lead to a gradually more egalitarian society. The compass, along with other innovations such as the cross-staff, the mariner's astrolabe, and advances in shipbuilding, enabled the navigation of the World Oceans, and the early phases of colonialism. Other inventions had a greater impact on everyday life, such as eyeglasses and the weight-driven clock.
Which inventions of the period had a great impact on everyday life?

Answer: eyeglasses and the weight-driven clock

Problem: Martin Luther, who initiated the Protestant Reformation, said: "Mother Mary, like us, was born in sin of sinful parents, but the Holy Spirit covered her, sanctified and purified her so that this child was born of flesh and blood, but not with sinful flesh and blood. The Holy Spirit permitted the Virgin Mary to remain a true, natural human being of flesh and blood, just as we. However, he warded off sin from her flesh and blood so that she became the mother of a pure child, not poisoned by sin as we are. For in that moment when she conceived, she was a holy mother filled with the Holy Spirit and her fruit is a holy pure fruit, at once God and truly man, in one person." Some Lutherans, such as the members of the Anglo-Lutheran Catholic Church, support the doctrine.
