Just as in the case of the Lectionary, after approval by the United States bishops the revised Sacramentary must be sent to Rome for approval by the Congregation for Divine Worship. Knowing the speed with which the curial offices work we can expect approval to take some time. But the point is that more change lies ahead. And anyone who has been around since the end of Vatican II knows that changes of any kind can provoke strong reactions and occasion emotional upsets. Change can divide churches and congregations.
Parties can develop.
Insults and recriminations are exchanged. Much of that occurs because change is introduced without adequate explanation or preparation. Their reason is one that should always be considered in adapting the liturgy. The Christian people should not have liturgical changes suddenly and arbitrarily foisted upon them without catechesis at the whim of the pastor or director of the liturgy. Huels goes on to say acceptance of change can be achieved only through catechesis, taking all the time necessary to explain change and building consensus for it.
