If you are unable to go, you could have still received indulgences if you prayed at a specified place of worship dedicated to the "Madonna of Lourdes." But this one was a limited 10-day offer from February 2-11, so if you missed this chance, better get your plane or boat tickets!
The whole idea of purgatory is against the gospel of Christ. Christ died to purge our sins, so what is purgatory for? And just where is it found in the Bible? Here is what I DO find in the Bible:
“Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high.” Hebrews 1:3
“But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.” 2 Peter 1:9
Purgatory has always been a method Rome has used for controlling their people. It has also been a method by which the Roman church has enriched itself selling indulgences to shorten time spent in purgatory.
Our sins have been purged by Christ already. To say otherwise is no less than heresy.
