I was always taught that there are four - and only four- requirements for a valid Mass:
- Proper Matter
- Proper Form
- Proper Minister with the
- Proper Intention
Our pastor stated that, in addition to these requirements, the celebrant must also consume a Host which was consecrated at that specific Mass. If he does not, the entire Mass is invalid, and transubstantiation does not occur.
I would tend to disagree, simply because I don’t believe you can “undo” something that has already taken place.
Is our pastor’s assertion correct?
