I sometimes get that feeling when I run across someone's personal blog, and it hasn't seen updates in quite a long while (yeah, like in ten years or so). However, as with most of the other replies here, I tend to just assume they've lost interest and moved on.
I've had some blogs like that myself, and I'm certainly still alive (I hope, lol!) Some of them already gone with the sites themselves like Multiply, if you ever remember that, also, Friendster blogs—all this in the late 2000's and early 2010's. Then there's some Wordpress blogs I used for a while back in 2015~2018. I just got lazy, lost interest, and so left them in the dust.
Thus, yeah, I simply assume they're doing just fine, and have just moved on with their lives.
However, there's a different feeling for when I browse the blog/social media profile of someone I definitely knew has already passed on. It hits different. It's like a frozen snapshot of their life. Their final post just there. A lot of times, the final post doesn't even indicate anything. Their lives just went on as normal until it didn't, and it just hits me differently than someone who I would just assume have just stopped posting.
Oh, a lot of Filipinos can be quite cultural in their Catholicism.
As far as my own experience goes, catechism in Philippine public schools is more of a guy from the nearby church gives a series of weekly lectures that students don't really pay attention to in order to have their first communion. And then after confirmation is treated more of a rite of passage than anything. Even my peers from Catholic schools aren't that much better either, but they do have allotted time for religious teaching (or indoctrination). As far as people I know are concerned, they don't take it seriously either.
There is no such thing as a Sunday school here, at least nothing that I know of.
There might be some people really serious about their Catholicism, but they're few and far between. For a lot of people, going to church is for the Christmas eve mass (on night of the 24th of December), and maybe the Easter day mass, and sometimes even for their birthday (which is basically: go to church and pray for a bit, light a candle, etc.) However, going to church every Sunday is not something a lot of people do. And even when they do, not a lot pay attention to the homily and most just go through the ceremony and motions.
However, we can be pretty wild with our devotions: the Black Nazarene being the most well-known. Thousands of people flock to its yearly procession. And then there's the infamous vows of being crucified during the yearly Lenten reenactment of Christ's crucifixion in certain town and localities.
And then there's our love of religious paraphenalia. Lots of Filipino homes have an altar with figures of their preferred saint alongside the icon or statue of the virgin Mary, Sacred Heart of Jesus and/or Jesus on the cross. This altar also has a candle (unlit, for safety, but sometimes lit for a few hours on certain days). This is also where some novena booklets, rosaries, and other blessed (as in sanctified by a priest in a special prayer at the end of novena masses) religious paraphernalia are placed.
Despite this outward show of religion, we barely know anything of it. Whatever little we may know of our religion mostly comes to us via whatever our parents teach us, if at all, or that scant cathecism given to us before our first communion. It's no wonder then, that most of us don't have any idea what our religion requires us to believe, or whatever the bible says. The bible might sometimes be part of the family altar, but often, it's just there to gather dust.
Just a disclaimer though, while I count myself among the people I described, I later on became agnostic. However, only my partner (who is more of a Reddit atheist, btw) knows that.
