I. What is This Sacrament Called?

From The Catechism of the Catholic Church

1423
It is called the sacrament of conversion because it makes sacramentally present
Jesus’ call to conversion, the first step in returning to the Father⁵
from whom one has strayed by sin.
It is called the sacrament of Penance, since it consecrates the Christian
sinner’s personal and ecclesial steps of conversion, penance, and satisfaction.
