The Council of Nicaea, held in 325 AD, was a gathering of bishops and church leaders convened by the Roman Emperor Constantine I to settle doctrinal disputes within the Christian Church. The council was attended by around 300 bishops from throughout the Roman Empire.

The primary issue discussed at the council was the nature of Jesus Christ: whether he was divine or human, or a combination of the two. The primary dispute was between Arius, a theologian from Alexandria who believed that Jesus was a created being and subordinate to God the Father, and Athanasius, a bishop from Alexandria who believed that Jesus was co-eternal and consubstantial with the Father.

After much debate and discussion, the council affirmed the divinity of Jesus Christ and adopted the Nicene Creed, which is still recited by many Christian churches today. The creed affirms that Jesus Christ is "begotten, not made, of one substance with the Father," and is therefore fully divine.

The council also established rules for the observance of Easter, condemned the practice of castration (which was sometimes practiced by Christian ascetics), and established guidelines for the ordination of bishops and priests. Overall, the Council of Nicaea was a significant moment in the history of Christianity, as it helped to establish a more unified and orthodox doctrine within the Church.<|im_end|>

On Friday, October 13, 1307, scores of French Templars were arrested, including the order’s grand master Jacques de Molay.

Many of the knights were brutally tortured until they confessed to false charges, which included heresy, homosexuality, financial corruption, devil-worshipping, fraud, spitting on the cross and more.

A few years later, dozens of Templars were burned at the stake in Paris for their confessions. De Molay was executed in 1314.

Under pressure from King Philip, Pope Clement V reluctantly dissolved the Knights Templar in 1312. The group’s property and monetary assets were given to a rival order, the Knights Hospitallers. However, it’s thought by some that King Philip and King Edward II of England seized most of the Knights Templar’s wealth.<|im_end|>

The Council of Nicaea was a significant event in the history of Christianity, and it took place in 325 AD. The Council was convened by Emperor Constantine I to resolve a dispute within the Christian Church regarding the nature of the Trinity and the divinity of Jesus Christ.

Before the Council of Nicaea, there were several theological disputes within the Church concerning the nature of Jesus Christ. Some Christians believed that Jesus Christ was fully divine, while others believed that he was a human being with some divine attributes. This disagreement led to a schism within the Church and threatened to undermine its authority and unity.

The Council of Nicaea brought together bishops from across the Roman Empire to debate and clarify the nature of the Trinity and the divinity of Jesus Christ. After months of discussions and debates, the Council produced the Nicene Creed, which became the standard definition of Christian doctrine for centuries to come.

The Nicene Creed declared that Jesus Christ was "begotten, not made" and was "of one substance with the Father." This statement affirmed that Jesus Christ was fully divine and was distinct from other created beings.

After the Council of Nicaea, there were several other councils held throughout the following centuries to address theological disputes and clarify Christian doctrine. Some of the most important of these included the Councils of Ephesus (431 AD) and Chalcedon (451 AD), which dealt with issues related to the nature of Christ and the relationship between his divine and human natures.

Overall, the Council of Nicaea was a pivotal moment in the history of Christianity. It helped to establish a clear and unified understanding of the basic tenets of Christian faith and provided a framework for future theological debate and discussion.<|im_end|>
