§1. The ordinary minister of baptism is a bishop, a presbyter, or a deacon, without prejudice to the prescript of can. 530, n. 1.
§2. When an ordinary minister is absent or impeded, a catechist or another person designated for this function by the local ordinary, or in a case of necessity any person with the right intention, confers baptism licitly. Pastors of souls, especially the pastor of a parish, are to be concerned that the Christian faithful are taught the correct way to baptize.
