What exactly do they mean by stricter?

A recent article in the ChristianPost.com, reports the rising tensions in the Church of Finland, a reportedly Lutheran church body. The main source of tension, a group of pastors becoming increasingly vocal in their opposition to women being ordained. These brave men are taking an increasingly unpopular stance and it would appear from the article are so firm in their stance as to refuse to work with any woman calling herself a pastor. Being that their church body is an organ of the state they have placed themselves in danger of legal action, because they are discriminating on the basis of gender. It is nice to see people standing up for what they believe despite the unpopularity of their position. With the likely actions they face these brave men need our prayers and support.
