Wow, so you were here in the late 50's! I imagine a lot has changed and I assume the rule of the Catholic Church is not as dominant as it was under General Franco. I hope I can learn more one day, personally I didn't know Anglicans practice Epiphany until your post.
Spain was a very different place.
It was national socialist. But more socialist than fascist. The falangistas were few in number and any parades and meetings were some what secretive.
The Church rule applied everywhere. Males had to wrap towels around them selves at swimming baths, girls could not expose their arms and shoulders in the street, If parents did not attend mass their children could not attend school.
You could not resign your job with out permission of both your employer and the syndicato. Your employer had to pay for your medical and dental care.
What ever people say now, the people then were happy and no way downtrodden.
With the exception of ex communists, who could not get a job that put them in charge of any one else, and had numerous other restrictions. The civil war was still a recent memory for many.
The Civil guard and police were everywhere, My then girlfriends father was a chief of the secret police. Crime of any sort was very rare indeed.
Anglican practises are very little different to Catholic ones,though what they believe can be different.
The Anglicans only celebrate the Epiphany with a Mass ( communion) it is not a lay celebration. It is like an ordinary Saints day, not a holiday.
I am surprised people could even have girlfriends/boyfriends, I assume you had to have a 3rd person present.
