Minimalism, Catholic Style

 The questions - Are Catholics obliged to receive Communion at every Mass they attend? And what about Confession?

Can.  920 §1. After being initiated into the Most Holy Eucharist, each of the faithful is obliged to receive Holy Communion at least once a year.

§2. This precept must be fulfilled during Easter season unless it is fulfilled for a just cause at another time during the year.

 Can. 989. After having reached the age of discretion, each member of the faithful is obliged to confess faithfully his or her grave sins at least once a year.
