1st Century Christians vs. Modern Day Christians


Just analyzing, studying, observing, questioning, seeking and praying about this walk of life and the belief in "Christianity"...

If the 1st century Christians (Paul and the disciples) came to a modern day christian church today, will they be able to recognize it???

What day did Yeshua (Christ), Paul and the disciples observe?
What holidays did the Lord, Yeshua obseve?
What did Yeshua consume and not consume?


Just asking.....while observing :)
