DOL 344, which is a letter from the Sacred Congregation for the Clergy, specifically of Cardinal J. Wright to Cardinal J. Döpfner (President of the German conference of bishops) on preaching by the laity, dated 20 November 1973.
Continuing with the norms provided by the document:
[2957] 1. In places lacking a priest or deacon, bishops are to choose layperson who will be empowered to give a homily during the celebration of the word of God so that on Sundays and holydays of obligation the faithful may receive help to sanctify the day.
[2958] 2. a. During a Mass the celebrant normally gives the sermon.
b. But a celebrant may be physically or morally prevented from fulfilling this function, no other priest or deacon may be available, and thus the faithful may be deprived of the spiritual help coming from the word of God. In such a case of compelling or reasonable need, bishops have the power to grant to laypersons the faculty to preaching even during a Mass.
c. Bishops are empowered to grant the same faculty when on a particular occasion (for example, celebrations on behalf of the Christian family, to promote works of charity or foreign missions, or other celebrations at the discretion of the bishop) laypersons are available who have special qualifications and whose words are likely to be effective.
[2959] 3. If circumstances permit, the celebrants gives an introduction or conclusion to sermons by the laity.
- To empower them to exercise the office of preaching at liturgical services, laypersons need to receive from the bishop a canonical mission, that is, delegation.
When the faculty to preach is to be of extended duration and in those cases indicated in no. 2, b and c, the bishop in person is to bestow the canonical mission. He may grant the faculty to subdelegate this canonical mission only to assistant bishops, vicars general, and episcopal vicars.
The bishop has the power to revoke the canonical mission for what he judge to be well-founded reasons.
[2960] 5. The appointment of laypersons must follow to the letter the rules to be issued by the conference of bishops. Criteria of selection must be, besides the requisite knowledge, a Christian manner of life and docility toward the Church’s magisterium and lawful local pastors.
[2961] 6. In the case of those who have returned from the clerical to the lat state, the norms of the Congregation for the Doctrine of Faith (AAS 63 [1971] 308, no. 4 b) apply.
DOL 307 no. 2561]
[2962] 7. The present rules, amending
Codex Iuris Canonici can. 1342, § 2, are given as an experiment and will remain in effect as the petition requests for four years. At the end of this period the conference of bishops will submita report of the results to the Holy See.
[2963] 8. Because of the seriousness of the matter, each bishop of West Germany before putting the present faculties into effect must first hear the opinion of the priests’ council.
Pope Paul VI has graciously approved the present rules, trusting that, with any kind of abuse being prevented, this apostolic concession will truly serve to the advantage of the faithful of Germany.
Here is
DOL 215 (Reply from the Pontifical Commission for the Interpretation of the Decrees of Vatican Council II to a query on the General Instruction of the Roman Missal no. 42, 11 January 1971), the first document referred to (in paragraph 2954):
[1768] Query: The words in the General Instruction of the Roman Missal no. 42, “The homily should ordinarily be given by the celebrant,” put into practice the prescriptions of the Constitution
Sacrosanctum Concilium art. 52 and the Dogmatic Constitution
Dei Verbum no. 24 (see also the Motu Proprio
Sacram Liturgiam, 29 January 1964, III, and the Instruction of the Congregation for Divine Worship
Liturgicae instaurationes, 5 September 1970, no. 2c). Should these words be interpreted in the sense that those also who are neither priests nor deacons, both men and women, but take part in the liturgy, may give the homily?
Reply: No.
At an audience granted to the undersigned Cardinal President, 11 January, 1971, Pope Paul VI confirmed and approved these decisions and ordered their publication.
And here’s the paragraph mentioned in paragraph 2961, from
DOL 307, Norms from the Sacred Congregation for the Doctrine of the Faith to be used by the curia of a diocese or of a religious institute to prepare cases for reduction to the lay state with dispensation from the obligations of holy orders, 13 January 1971: AAS 63 (1971) 303-308 (excerpt):
[2561] The Ordinary charged with informing the petitioner of the rescript is to urge him earnestly to take part in the life of the people of God in a way consonant with his new way of life, to give good example, and to show himself to be a loving son of the Church. At the same time the Ordinary is to inform the petitioner that any priest reduced to the lay state and dispensed from his obligations is barred from:
a. exercising any function of holy orders, except those indicated in can. 882 and 892, § 2;
b. exercising any liturgical function in celebrations with a congregation, in a place where his condition is known, and from ever giving the homily; …]
That’s all. Read and ruminate and discuss.
