Breach of confidentiality

Should Pastors and other church workers be called to account for breach of confidentiality they committed? To date, I have not heard of any Indonesian church who asked its pastors and bible teachers to sign a confidentiality agreement. Meaning that any information that they hear from counseling session with church members, formal or informal, will not be divulged to anybody without the other's consent. I believe it is time that the Indonesian churches have some sort of guidelines for its pastors and workers. It is unethical to tell others personal problems that they hear from church members. It is even worse when a pastor uses it as an illustration in his or her sermon without permission.
In a sermon I heard, a young couple who were about to be married were mentioned. Although the said couple and I lived in different countries, and we did not know one another, enough details were given that I could somehow connect the dots and pin-point which couple the pastor was referring to with some degree of precision. The illustration, unfortunately, painted a rather unfavorable picture of the couple as spoiled young adults from rich families who don't know how to count their blessings and are whining over something that others would have rejoiced over.

Why did the pastor do that? Was it unintentional? Was he clueless about how inappropriate he was? Or was he smarting over not being asked to officiate the wedding?

At any case, guidelines should be established. It does occur to me that maybe others don't share the same opinion on the issue. Maybe, I have lived too long in a western world and my mindset is just too westernized. Maybe, it's because confidentiality is a big issue in the helping profession I am in so my level of expectation is skewed. What do you think?
