How did Palm Sunday become recognized as a holy day?

I don’t mean, how did it get put on the Church calendar,
- but why do we celebrate it?
• Palm Sunday is not like Christmas, Good Friday, or Easter
◦ these were the major events in Jesus’ life and ministry
• but Palm Sunday is not noteworthy in the same way
◦ in fact, if you’ll excuse the expression, it sort of fizzled out
◦ by the end of the week, Jesus had been crucified
- I’ll share with you why I celebrate Palm Sunday
• because this was only time that Jesus permitted public recognition
◦ until now, he told his disciples to keep his identity a secret
• but on this day he allows people to celebrate who he is
◦ he wants this moment in the spotlight – he planned it
◦ it’s because Jesus wanted to be recognized that I remind myself to see and worship him for who he is
