Sorry to make one correction here. The Easter Triduum has been incorrectly held to be Holy Thursday, Good Friday and Easter Vigil. It is not - it is Holy Thursday, Easter Vigil and Easter Sunday. Again, **Catholics often incorrectly take Easter Vigil and Easter Sunday as the same mass, and consider one to be the subsitute for the other. ** It is not - we should be attending both as the story of the resurrection did not end with the empty tomb of the Easter Vigil but with the appearance of Jesus on Easter Sunday morning.
But, not a big deal to make that mistake as Catholics commonly make that mistake

. Still, I would like to see Easter Sunday morning mass to be as well attended and not just for those who cannot stay up for the Vigil mass.
