The first Catholic Scrutiny is a Lenten ritual for those preparing for Baptism (the Elect), focusing on the Woman at the Well (John 4) to highlight thirst, sin, and Jesus as the "living water" for new life, involving prayers, self-examination, and exorcism to cleanse the Elect of sin and worldly attachments before Easter. It's part of the OCIA (Order of Christian Initiation of Adults) process, teaching about sin and filling hearts with Christ's redeeming Spirit.
