Quiz about basic knowledge of Christianity

According to the teaching of the Church, in no way the efficacy of the Sacraments depends on the holiness or sinfulness of those who administer them. The doctrine stating that the Sacraments administered by unworthy ministers are invalid, belongs to the Donatist heresy. Donatism was condemned at the Church Councils of Rome (313) and Arles (314).

The efficacy of the Church's sacraments does not depend on the qualities of the concelebrant. I.e. if you come to confess your sins to a man who is close to holiness and righteousness, and he will forgive your sins, and if you come to a priest who is ten times more sinful than you, and this may well happen, and he reads a prayer over you and says that your sins are forgiven - they will be forgiven in the same way. You cannot say that this bishop has more forgiveness of sins than another bishop. It cannot be said that this bishop baptised the child for one hundred percent, and this bishop baptised the child only for fifty percent. The child will be baptised in both cases, the deceased will be buried in both cases. The bread and wine will become the Body and Blood of Christ, no matter how unworthy even the most unworthy priest administers the sacrament. Therefore, as far as worship and the administration of the sacraments are concerned, these criteria are irrelevant. Simply because it is not a human being who performs all this - God administers the sacraments. It is always an act of God. And the priest is used by God as an instrument that He uses.
