wow, i am serbian and i didn't know it!
i celebrate my 'slava' today, and also on the date when i became orthodox.
i was chrismated on the EO feast day of saint matthias, and his feast day in the coptic church is today,
and so i remember him both days!
i felt a special connection to him since just before i was orthodox, when i got to 'take the short straw' in an anglican service
where the minister was making a practical demonstration of how to 'draw lots' and i briefly took the role of saint matthias.
then, soon after i became orthodox, i was trying to find an icon to use as my picture on another website.
i did not recognise most of the icons at that time (!) but then saw saint matthias and was drawn to him.
this is why i still use him on this website too.
then AFTER that, i found out saint matthias was busy having his feast day when i was joining the church, so i was delighted!
(i also celebrate saint simon the stylite, and saint patriarch primus, the 5th coptic patriarch,
who are celebrated the same day in the coptic church)
i don't celebrate it with any special bread, but with prayers and rejoicing and with going to liturgy where possible.
may the prayers of saint matthias be with you all, and also the prayers of our dear departed patriarch shenouda 3rd,
who departed 3 years ago today.
