Part II, Article 11. The Minister of Baptism
Particularly praiseworthy is the faith with which many Christians, in
painful circumstances of persecution, or in missionary territories or in
special cases of necessity, have afforded and continue to afford the
Sacrament of Baptism to new generations of Christians in the
absence of ordained ministers.
Apart from cases of necessity, canonical norms permit the non ordained
faithful to be designated as extraordinary ministers of Baptism 
should there be no ordinary minister or in cases where he is impeded.
 Care should be taken however to avoid too extensive an
interpretation of this provision and such a faculty should not be
conceded in an habitual form.
Thus, for example, that absence or the impediment of a sacred minister
which renders licit the deputation of the lay faithful to act as an
extraordinary minister of Baptism, cannot be defined in terms of the
ordinary minister's excessive workload, or his non-residence in the
territory of the parish, nor his non-availability on the day on which
the parents wish the Baptism to take place. Such reasons are
insufficient for the delegation of the non ordained faithful to act as
extraordinary ministers of Baptism.
