This priest is deep into abuse and knows it. If you proceed with a heavy handed approach, you will be dismissed.
If you say and do nothing then exactly nothing will happen as well. So what to do?
Number one, stop all but a token donation to this parish and convince two or three others to do the same. Transfer this same money to a group that is true to the magisterium and evangelizing in our communities. These are the ones running silent retreats, and traditional celebrations such as a May Crowning.
Second, check out these references. Print a relevant section and hand it to the priest when you meet. Be gentle, but firm. Bless this priest as you depart.

Therefore no other person, even if he be a priest, may add, remove, or change anything in the liturgy on his own authority.

XI. Finally we wish to emphasize that—beyond what we in this apostolic letter on liturgical matters have either changed or have ordered carried out at the established time—regulation of the liturgy comes solely within the authority of the Church: that is, of this Apostolic See and, in accordance with the law, of the bishop. Consequently, absolutely no one else, not even a priest, can on his own initiative add or subtract or change anything in liturgical matters (CONSTITUTION, Article 22, paragraphs 1 and 3).

The faithful have a right to a true Liturgy, which means the Liturgy desired and laid down by the Church, which has in fact indicated where adaptations may be made as called for by pastoral requirements in different places or by different groups of people. Undue experimentation, changes and creativity bewilder the faithful. The use of unauthorized texts means a loss of the necessary connection between the lex orandi and the lex credendi. The Second Vatican Council’s admonition in this regard must be remembered: “No person, even if he be a priest, may add, remove or change anything in the Liturgy on his own authority.”(8) And Paul VI of venerable memory stated that: “Anyone who takes advantage of the reform to indulge in arbitrary experiments is wasting energy and offending the ecclesial sense.”(9)

The effectiveness of liturgy does not lie in experimenting with rites and altering them over and over, nor in a continuous reductionism, but solely in entering more deeply into the word of God and the mystery being celebrated. It is the presence of these two that authenticates the Church’s rites, not what some priest decides, indulging his own preferences.
Keep in mind, then, that the private recasting of ritual introduced by an individual priest insults the dignity of the believer and lays the way open to individual and idiosyncratic forms in celebrations that are in fact the property of the whole Church.
The ministry of the priest is the ministry of the universal Church: its exercise is impossible without obedience, hierarchic communion, ant the will to serve Got and neighbor. The hierarchic character and sacramental power of the liturgy as well as the respectful service owed to the believing community demand that the priest fulfill his role in worship as the “faithful servant ant steward of the mysteries of God”.
