A1 Whether God alone works inwardly in the sacraments?

A2 Whether the institution of the sacraments is from God alone?

A3 Of the power which Christ exercised over the sacraments;

A4 Whether He could transmit that power to others?

A5 Whether the wicked can have the power of administering the sacraments?

A6 Whether the wicked sin in administering the sacraments?

A7 Whether the angels can be ministers of the sacraments?

A8 Whether the minister's intention is necessary in the sacraments?

A9 Whether right faith is required therein; so that it be impossible for an unbeliever to confer a sacrament?

A10 Whether a right intention is required therein?
