A pastoral counselor needs to know the truth that sets people free, but that is not enough. They need to have found their own identity and freedom in Christ before they can lead others. No person can impart to others what they don't possess themselves. It is hard to specify a minimum requirement for godly character and pastoral skills. Titus chapter one and 1 Timothy chapter three specify the character requirements, but they can't be simply taught most pastoral skills are learned in the process of ministry.
Young seminarians have to start some time, and humbly learn from their mistakes.
