[quote=Toni]I have heard that for years. Because for years it has been the teaching. But I think that has changed. I at one point heard for Sunday Mass the latest was the consecration, but I believe the Gospel should be kept as cutoff. But am unsure if that has been changed.
If you read the link I supplied above from a Catholic Answers apologist you will see that any and all official cut off times disappeared after Vatican II because they were abused. People would either purposely come in at the last possible time or people would be overly scrupuluous and worry if say a car accident made them late.
To fulfil your Sunday obligation you are supposed to try to be there for the entire Mass. If an unusual circumstance happens and you are late, no problem. If you purposely show up late or do not adjust times you leave for Mass because you routinely show up late, then there is a problem.
As I said above, why take a minimialistic view of how long you should be at Mass. Do you want the Lord taking that view with you?
Being there by the Gospel is a good cutoff time to suggest that you really should go to another Mass, but it isn’t required.
What is required is that if you show up for Mass late even if the only thing you missed is the processional you should search your soul and determine if you made every effort to be there on time. If the answer is no, go to another Mass.
