5. Faced with the situation that has arisen I deem it my duty to inform all the Catholic faithful of some aspects which this sad event has highlighted.

a) The outcome of the movement promoted by Mons. Lefebvre can and must be, for all the Catholic faithful, a motive for sincere reflection concerning their own fidelity to the Church's Tradition, authentically interpreted by the ecclesiastical Magisterium, ordinary and extraordinary, especially in the Ecumenical Councils from Nicaea to Vatican II. From this reflection all should draw a renewed and efficacious conviction of the necessity of strengthening still more their fidelity by rejecting erroneous interpretations and arbitrary and unauthorized applications in matters of doctrine, liturgy and discipline.

To the bishops especially it pertains, by reason of their pastoral mission, to exercise the important duty of a clear-sighted vigilance full of charity and firmness, so that this fidelity may be everywhere safeguarded.(⁷)

However, it is necessary that all the Pastors and the other faithful have a new awareness, not only of the lawfulness but also of the richness for the Church of a diversity of charisms, traditions of spirituality and apostolate, which also constitutes the beauty of unity in variety: of that blended "harmony" which the earthly Church raises up to Heaven under the impulse of the Holy Spirit.

b) Moreover, I should like to remind theologians and other experts in the ecclesiastical sciences that they should feel themselves called upon to answer in the present circumstances. Indeed, the extent and depth of the teaching of the Second Vatican Council call for a renewed commitment to deeper study in order to reveal clearly the Council's continuity with Tradition, especially in points of doctrine which, perhaps because they are new, have not yet been well understood by some sections of the Church.

c) In the present circumstances I wish especially to make an appeal both solemn and heartfelt, paternal and fraternal, to all those who until now have been linked in various ways to the movement of Archbishop Lefebvre, that they may fulfil the grave duty of remaining united to the Vicar of Christ in the unity of the Catholic Church, and of ceasing their support in any way for that movement. Everyone should be aware that formal adherence to the schism is a grave offence against God and carries the penalty of excommunication decreed by the Church's law.(⁸)

To all those Catholic faithful who feel attached to some previous liturgical and disciplinary forms of the Latin tradition I wish to manifest my will to facilitate their ecclesial communion by means of the necessary measures to guarantee respect for their rightful aspirations. In this matter I ask for the support of the bishops and of all those engaged in the pastoral ministry in the Church.
