The way of the Cross is a traditional practice of thinking devoutly about the suffering death and Resurrection of Jesus. When we go through the way of the Cross, we remember that our sins caused Jesus to suffer and die. We also remember that Jesus' passion continuous today in the suffering humanity.
After Vatican II, many theologians suggested that the Resurrection be included to express the Paschal Mystery more fully. Some Theologians also proposed that the different stations reflect death. Thus, some included new sequences. Others kept the traditional sequence and merely added a fifteen station for the Resurrection.
The Booklet Presence: Prayer for busy People published by Saint Paul's Publications in 1991 has fourteen stations.
The pamphlet issued by Worlds and Life Publication in 1992 also has fourteen stations. Note the similarities and the differences between the two.
