Dear Parents and relatives
Dear believers in Christ
Our Savior invites us to leave everything, to cut all ties before ceasing to be his disciples.
He is our Redeemer, provides us with the grace of God and reveals the full truth.
By what we have – illuminated not by our merits but by His grace and strength – in less esteem respect for human ties that our fidelity to the Church instituted by Him, who is the only one who received the divine promise of durability.
Having grown up under the care of one of the few priests in Austria [who] resisted the wave of modernism and post-conciliar changes, I left my house in 1988 to enter the Seminary Zaitzkofen, persevered there – and [on] the June 25, 1994 I was ordained Priest of Jesus Christ in the SSPX.
Today, 19 years later, again follow the call to leave my spiritual home, away and abandon it. I do it for this reason only: the desire to be faithful to the truth and preserve intact the grace of the priesthood.
So what once was my spiritual home, is in ruins. For over a decade she [the Menzingen-denizens] has worked – part [in] secret, openly part in their destruction (1) ashamed of their origin (2), denying its founder (3), opening the doors to the enemy to occupy the Bastion (4 ).
See[ing] the facts is the duty of every rational person. You can no longer ignore this, now the truth is before all, and did not escape the eyes of many brothers who remain silent, but if you do not say anything, [you would thereby] seem to agree. However, the priest, by his ordination, has the duty of preaching
(5) for the benefit of the faithful. Who is [there] among the faithful for their divine calling and ordination, [who] can not think of departing or [holds their] head down or [waits] while [the] blasting [away from the] enemy strikes the souls of the faithful? [For to] Continue waiting would be a sin.
You can not expect an improvement of the situation of the current leaders of the Fraternity. Its manifestations are numerous and clear, even in recent times
(6). I do not respond to the Superior General has not signed anything, that everything continues as before: Its [actually, 'his'] Doctrinal statement of April 15 [the AFD] contains the abandonment or at least a substantial limitation [to the] established Lefebvre reservations regarding the teachings of Vatican II, of the new Mass, new sacraments and the laws of the neo-church.
Therefore, it makes no sense to expect future events or characters. No matter if or when the modernist Rome make the following raid Fraternity to carry on their leaders, since it is already weakened in its principles, so a full alignment is only a matter of time. Figuratively speaking: If you open the doors to the enemy [whether its that your] stronghold falls, or [else it is] reduced to ashes or [your traitorous action] helps the enemy to succeed, is the same. Boasts Alea Est. [Who is "Alea Est?"]
That the eternal and immortal God, the Father of our Lord Jesus Christ, accept my decision, confirm and bless the through the maternal intercession of Blessed that call for their unwavering faith.

the June 25, 2013
On the 19th anniversary of my priestly ordination.
[Notes]________________
1. "In the last 10 years, there has been a new situation" (Father Pfluger Conference 1.5.2012 to Actio Spes Unica)
Two. Very symptomatic has been a name change. From "Priesterbruderschaft St. Pius X" to "Piusbruderschaft". We have omitted the "Priester" (priest), "heilig" (san) and the name of the great anti-modernist Pope Pius X.
Three. In March 2012, the occupied reconcile modernist Rome, threatened the superior of the SSPX with excommunication for schism by a one-month ultimatum. Instead of deciding to reject the proposal of Rome, the Superior General made ​​a compromise text (Doctrinal Statement of April 15, 2012), which he said is based on similar language Archbishop M. Lefebvre May 1988. But he omits to say that the Archbishop withdrew his signature "protocol" of May 5 the next day it was signed.
4.GREC "between Catholics Reflection Group" [Group for Reflection among Catholics,
Groupe de Réflexion Entre Catholiques], an initiative of the then French ambassador [to Italy] in Rome, [founded in 1997 by Mr. Gilbert] Perot wanted to make a roadmap for the "necessary reconciliation" of the Catholic tradition and the post-conciliar Church from 1996 to 1997 and they had the consent of the responsible parties. See the book by Father Michel Lelong, who revealed these secret meetings in 2012 [15 years of semi-silence!]. See also how the General Chapter of the Society of 2012, completely softened and rendered ineffective some preconditions for future contacts with Rome.
May. "Oportet." Praedicare, praeesse "." (Roman Pontifical) [what?]
June. For example, in an interview with Bishop Fellay on the 25th anniversary of his episcopal ordination, the Superior says he sees no connection between the vision of Archbishop Lefebvre to save the priesthood, and the episcopal consecrations. There it is, this strange statement that the consecrations are vital to the Brotherhood but not essential.The first assistant to the Superior General, said in a lecture in Vienna on June 16, 2013: "No one can say how Archbishop Lefebvre act today." He can speak for himself. Catholic But if the truth does not change and Archbishop Lefebvre was a staunch defender of the truth, then it is sure and certain, that the Archbishop had also declined in 2012-2013, commitment rotten practical agreement with Rome in 2012 or 2013. After his experiences in 1987/88 would not have or even expected.

I hope TheRecusant can take a stab at a decent translation. This looks
really good for the Resistance -- a whole new flavor in how to approach
the incriminating events of the past 2 years in context of hidden data from
the previous 10 years.
