If you know someone who is called to be a saint, and you have responsibility over that person, (for example, you are a parent forming children, or a husband or wife), you must look at several things.
One, you are also called to holiness and, therefore, you must cooperate with graces. We are all called to be saints.
Two, if you are willing to follow the course to holiness, then, you have a right and duty to work with those, but only those, who God has given you authority over. For example, a teacher or tutor, may have authority over students, given to him by God and parents.
But, parents are the main and first formators.
Wives and husbands are called to help each other get to heaven.
Three, one cannot give what what does not have.
Four, we are not to meddle in the lives of others for whom God has not given us responsibility. That is "out-of-order".
Five, God will call us to account for those souls to whom we have been given reprehensibility, but we are not to assume authority over others. God has called priests and some lay spiritual directors to this task. It is not out business to become spiritual leaders unless God clearly calls us to this.
Which is why, because of this blog, I must be hard on myself and stay very close to God.
St. Paul has much to say on the subjects of holiness and authority.
