Pastoral care is an ancient model of emotional and spiritual support that can be found in many cultures and traditions. It has been described in our modern context as individual and corporate patience in which trained pastoral carers support people in their pain, loss and anxiety, and their triumphs, joys and victories.

It historically is the ministry of care and counseling provided by pastors, chaplains and other religious leaders to members of their church or congregation, or to anyone within institutional settings. This can range anywhere from home visitation to formal counseling provided by pastors who are licensed to offer counseling services.
