They are being completely illogical, that small number of people who wrongly think that there is a discrepancy between believing in The Divine Mercy and being a Sede.
Sedes understand that Benedict XVI is an Antipope.
The Divine Mercy is a Catholic Devotion approved of by the Catholic Church in the A.D. 1930’s.
So the two beliefs are entirely compatible.
Pope Pius XII believed in The Divine Mercy and defended The Divine Mercy and performed a Ceremony Blessing The Image of The Divine Mercy. The Divine Mercy was given extensive Imprimaturs by the Catholic Church of Pope Pius XI and also under Pope Pius XII.It was banned several times by Antipope John XXIII.
For those who are concerned by this, be reassured by the fact that under Paul VI the Church completely lifted the bans.
If you believe that John XXIII was Pope, you probably also believe that Paul VI was a valid Pope as well.
John Paul II canonized S. Faustina Kowalska. If you believe that John Paul II was a valid Pope, then you have to accept his canonizations:If anyone dared to assert that the Pontiff had erred in this or that canonization, we shall say that he is, if not a heretic, at least temerarious, a giver of scandal to the whole Church, an insulter of the saints, a favorer of those heretics who deny the Church’s authority in canonizing saints, savoring of heresy by giving unbelievers an occasion to mock the faithful, the assertor of an erroneous opinion and liable to very grave penalties.
And:
To suppose that the Church can err in canonizing, is a sin, or is heresy, according to St. Bonaventure, Bellarmine, and others; or at least next door to heresy, according to Suarez, Azorius, Gotti, etc.; because the Sovereign Pontiff, according to St. Thomas, is guided by the infallible influence of the Holy Ghost in an especial way when canonizing saints.
So if you accept John Paul II as Pope, you have to accept that he infallibly canonized
Saint Faustina Kowalska.
Many Sede laity, priests, and also Sede Bishops believe in The Divine Mercy.
Also, The Divine Mercy was given many Imprimaturs under Pope Pius XII. An example of these many Imprimaturs for The Divine Mercy:
Reference is to the imprimatur of two publications: 1. An image of Jesus with the Chaplet to The Divine Mercy on the back, for which Fr. Sopocko obtained permission in Vilnius on Sept. 1, 1937 (No. R. 200/ 37); 2. A small pamphlet under the title Chrystus Krol Milosierdzia (Christ King of Mercy), which included the novena, the chaplet and the litany to The Divine Mercy. The imprimatur was granted by the Metropolitan Curia in Cracow (L. 671/37). Both were published by the J. Cebulski Publishing House, 22 Szewska St., Cracow.
(The Diary of Saint Maria Faustina Kowalska. Footnote 208.)
Another Imprimatur for The Divine Mercy:
Probably Father Sopocko's pamphlet called Milosierdzie Boze (Studium teologiczne-praktyczne) [The Divine Mercy (A Theological - Practical Study)], published in Vilnius in 1936. Imprimatur was given by Bishop Romuald on June 30, 1936, No. R. 298/36 (A. SF.). The cover of the pamphlet showed a color copy of Eugene Kazimierowski's image painted in Vilnius.
(The Diary of Saint Maria Faustina Kowalska. Footnote 136.)
When the Church has given Imprimaturs, we are supposed to take notice of those.
I have proved elsewhere on CathInfo that Pope Pius XII believed in The Divine Mercy and promoted it.
I have proved elsewhere on CathInfo that Cardinal Ottaviani believed in and promoted The Divine Mercy.
Pope Pius XII believed in The Divine Mercy.
Cardinal Ottaviani believed in The Divine Mercy. Cardinal Hlond, the Primate of Poland believed in The Divine Mercy.
Cardinal Prince Adam Sapieha, Cardinal of Poland, believed in The Divine Mercy.
Archbishop Romuald Jalbzykowski (S. Faustina Kowalska’s Bishop) believed in The Divine Mercy.
The Ordinary of Gorzow, Zygmunt Szelazek, believed in The Divine Mercy.
Many Polish Bishops believed in The Divine Mercy.
Many other Bishops throughout the world believed in The Divine Mercy.
Father Michael Sopocko, S. Faustina Kowalska’s Spiritual Director and the Convent’s Confessor, believed in The Divine Mercy.
Father Joesph Andrasz, S. Faustina Kowalska’s convent’s other Confessor, believed in The Divine Mercy.
Mother Irene Krzyzanowska, S. Faustina Kowalska’s Mother Superior, believed in The Divine Mercy.
By A.D.1953, some 25 million pieces of Divine Mercy literature had been distributed around the world.
From
http://thedivinemercy.org/library/article.php?NID=3466 The Divine Mercy was an Approved Devotion in the Pontificates of Pope Pius XI and Pope Pius XII as can be shown by the fact that The Divine Mercy was granted many Imprimaturs throughout the world.
Some Examples of Imprimaturs given to The Divine Mercy:
Bishop Romuald gave the Imprimatur to The Divine Mercy Devotion in A.D. 1936.
The Novena to The Divine Mercy, The Chaplet of The Divine Mercy, and The Litany to The Divine Mercy were all given the Imprimatur by the Metropolitan Curia in Cracow in A. D. 1937.
THUS, THE DIVINE MERCY IS AN APPROVED DEVOTION OF THE PRE- CONCILIAR CATHOLIC CHURCH OF POPE PIUS XI AND POPE PIUS XII.
The pre-conciliar Catholic Church in the time of Pope Pius XII in the A.D. 1950s established a Religious Order for the purpose of spreading The Divine Mercy:
“The Congregation of the Most Holy Lord Jesus Christ, Merciful Redeemer”
They were also known as the "Congregation of the Merciful Redeemer."
They are now called "The Congregation of the Sisters of Merciful Jesus" and have over 30 Religious Houses spread through more than 10 different countries.
This is their website:
http://www.faustina-message.com/On it your can see the Miracle that The Holy Face of Jesus from The Shroud of Turin exactly matches The Holy Face of Jesus from The Divine Mercy. This order was inspired by the Directions given by Our Lord to S. Faustina Kowalska for the founding of such a community.
It was founded because S. Faustina told Pope Pius XII’s pre-conciliar Catholic Church that Our Lord wanted this Order to be founded.
Thus we can see the very great degree of approval given to The Divine Mercy by the pre-conciliar Catholic Church in the lifetime of Pope Pius XII.
Therefore Catholics should believe in The Divine Mercy.
Therefore Sede Catholics and other traditional Catholics should believe in The Divine Mercy.

http://www.saint-faustina.com/Diary/footnotes.html Do not be robbed of one of the final true Devotions from God, which is entirely accepted by the Catholic Church.
Do not be tricked by the banning by Antipope John XXIII, which was lifted by Paul VI anyway.
The Divine Mercy is from God. It was believed in by Pope Pius XII. It is very powerful.
