Background

Christianity is the most widespread religion in the world. The religion was founded by Jesus of Nazareth, in the Land of Israel more than two thousand years ago (the year 0 - Anno Domini - AD - the year of our Lord, was determined as the year of Jesus’ birth).
According to the Christian belief, Jesus was born in Bethlehem, to his mother Mary (Miriam) while she was a virgin (conceived by the Holy Spirit). After he went around the Land of Israel and spread his teachings, and the fact that he is the Son of God, he was handed over to the Roman authorities, and executed by crucifixion on Calvary (Golgotha hill) .

Jesus’ journey of suffering (Via Dolorosa) is the road in Jerusalem that he walked from the place where he was sentenced to his crucifixion , , .

The cross has since been considered a symbol of the Christian religion, and it appears in many and varied forms, and is placed in almost every church , also it is found in many symbols that are not necessarily related to Christianity today ,

Christianity believes in the "Holy Trinity" the Father = God, the Son = Jesus and the Holy Spirit = the divine presence existing in the world .

The holy book of Christianity is the "New Testament" in addition to the Old Testament which constitutes the Bible. In the New Testament the life of Jesus is described, as well as the actions of the apostles.

The Twelve Apostles
The disciples of Jesus who were chosen after his death to spread his gospel. It is believed that they were the ones who were present at the "Last Supper" (the meal he ate before his sentence and where he met his disciples for the last time).
The most important of them was Peter who was also considered the first Pope , and after him the Basilica of Saint Peter in the Vatican is named
Another apostle who was not in the 12 apostles, and never met Jesus is Paul, one of the authors of the New Testament .

Christian denomination
Over the years, there have been divisions among the believers of the Christian religion, so that there have been variations of the worships, the heads of the religion, and more.

Catholic Church

Protestantism
A stream in Christianity that arose in the 16th century AD under the leadership of Martin Luther and Jean Calvin (the Reformation), who challenged all the worship that had been sanctified over the years in Catholic Christianity, and called to act only according to the Holy Scriptures (the Bible and the New Testament).
In this church there are several main sub-currents:
The Anglican Church Although it originates from the Catholic Church, after the Reformation, King Henry VIII severed ties with the Pope. The head of the church is the Archbishop of Canterbury.
Baptists A church that was established in the 17th century and the main thing is the baptism ceremony that is done at maturity, so that acceptance into Christianity is done with knowledge and faith, in contrast to the accepted practice where baptism is done for babies who are not aware of the faith.
Evangelicalism A movement that arose in the 18th century and its believers are particularly pious, and stay away from the pleasures of life. This church is very common in the United States.

Eastern Orthodox Church

It is headed by patriarchs and archbishops subordinate to the countries in which they are located.
