Growing up my grandparents, who raised me, brought me up to attend the Union Presbyterian Church. I eventually joined, but fell away as the years passed. This church did celebrate Maundy Thursday...I don't recall too much about it, but I think there was a service on that night...and always a Good Friday service the next day, in the afternoon.
I believe it commemorated the Last Supper...and I think another church I attended years later - Union Center Christian Church - had a Passover feast of some sort...which I never attended. Of course Good Friday was about the crucifixion of Christ...my grandmother said, many times, "It always rains on Good Friday."
I believe I did attend a few Maundy Thursday services, but I don't remember too much...my twin sister may...I will ask her.
The church I grew up in was dismal and negative...no energy at all, in fact, I never learned about salvation through Jesus Christ until I accidently attended a Baptist church. The Presbyterian church hymns were awful and, to me, the people appeared to be a bunch of mannequins in church pews.
This probably is not much help, but I do not attend church at all now - I haven't in years...I write personal letters to God, and communicate to Him with prayer lists on my own.
I have great faith in God, but not because of church, and I do believe when I pass into eternity I will be in Heaven, not because of my works on earth but because of God's love, grace and mercy for me.
Thanks for a great question. Blessings, Sparklea :)
