Translation of "Faculty" in Chinese

I study comparative religion in the arts faculty at Turku University.

我在图尔库大学文化系学习宗教学。

Recently I attended the wedding of a Chinese friend. The bride and groom had been classmates at university, and both graduated from the Chinese faculty. They've already been together for five years.

最近我参加了一个中国朋友的婚礼，新郎和新娘是大学同学，都是中文系毕业的，他们已经恋爱五年了。
