God doesn’t have a timeline.
It took nearly 500 years for St. Joan of Arc to be recognised as a saint.
It took Pope St. John Paul II only a few years.
So? For God “A thousand years in (His) sight is as yesterday, which is past, and as a watch in the night.”
The Church is guided by the Spirit to acknowledge some saints while others will not be known until the Last Judgment. I don’t question why God reveals some now, or when He reveals them. I’m glad to know about people, even people who may be very different from me, who had heroic virtue and pleased God enough to be saints. It can help me try to do the same.
