From the website of the French District of the Priestly Fraternity of Saint Peter (FSSP):
Offering up our Lent for Catholic Unity(Last modification: 02.24.2012, 0827)
In this Lenten season, some among our friends have taken the initiative of offering up their struggles and sacrifices for reconciliation and unity between all Catholics.
At a moment in which the dialogue between the Society of Saint Pius X [SSPX] and the Holy See reaches a decisive point for the future, the District of France [of the FSSP] encourages its friends to double their fervor in prayer.
P.S. reading material to enrich our meditation: the Message of Benedict XVI for Lent.
