how has christianity teachings of one text (the Bible), divided into so many denominations?

I am not so certain the text did it. Social and cultural conflicts, as well as power greed, probably had much more to do with it than the intrepretations of the text.

I remember well the divisions in North Ireland, in which Catholics and Protestants were fiercly divided, but the issue mainly was cultural and geopolitical, not religious.

The division of Christianity into various denominations can be attributed to several factors, including differences in interpretation of the Bible, theological perspectives, cultural influences, historical events, and individual preferences. Here's an explanation of how these factors contribute to the creation of different Christian denominations:

1. Interpretation of the Bible: The Bible is a complex text, and different individuals and groups may interpret its teachings differently. Disagreements can arise over theological doctrines, moral issues, and practices. These differing interpretations can lead to the formation of separate denominations that align with specific interpretations.

2. Theological perspectives: Various Christian denominations emphasize different theological doctrines and place different levels of importance on certain beliefs. These differences can stem from disagreements on topics such as salvation, sacraments, the nature of God, predestination, and the role of the Church. These theological variations often lead to the formation of distinct denominations.

3. Cultural influences: Christianity has spread across the globe and encountered different cultures, leading to the integration of local customs, traditions, and beliefs into the practice of the faith. This cultural diversity has contributed to the development of denominations with regional or ethnic identities.

4. Historical events: Throughout history, significant events such as church councils, religious reforms, conflicts, and schisms have influenced the formation of different Christian denominations. For example, the Protestant Reformation in the 16th century resulted in the formation of Protestant denominations separate from the Roman Catholic Church.

5. Individual preferences: Personal convictions, preferences, and individual interpretations of Scripture can also contribute to the emergence of new denominations. Some individuals may feel their beliefs and practices are not adequately represented by existing denominations and choose to establish their own.

It is important to note that while there are numerous denominations, there are also common beliefs and practices that unite Christians across different denominational lines, such as belief in the divinity of Jesus Christ and the importance of love, compassion, and spreading the Gospel.
