Well, they are not only having 'concerts' but "Free Sunday Community Breakfast" to bring in people on Sunday, I don't even want to speculate on that.

is salvation by a day or by grace through faith? are all who go to church on sundays going to be lost because they go to church on sundays?

Obedience to God is a result of salvation not as a means of salvation for Ephesians 2:8-9 clearly says that we are saved by faith and not by works, and James 2:20-21 also clearly states that faith without works is dead and that Abraham was justified by works.

This, however, is another topic for another thread.

it would seem so, but the "apostasy" rick is describing is "going to church on sundays". but that is NOT apostasy, but rather returning to the church as it was in its early glory. see acts 2: 46, "So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart"

the early church was actually engaging in "Free Sunday (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday) Community Breakfast" and moreover God was blessing them as it is written, "And the Lord added to the church daily those who were being saved." acts 2:47

the obsession and zealousness for saturday is going to cause massive division among sda to the point that many will cast out (and have killed) the innocent and think they are doing God service.

john 9:16, "Therefore some of the Pharisees said, This Man is not from God, because He does not keep the Sabbath. Others said, How can a man who is a sinner do such signs? And there was a division among them."

I think that was more a "daily worship" program, which we should all have. Every day we need to spend time in worship. Prayer breakfasts during the week are great, as are afternoon bible studies.

This however isn't to be confused with a special DAY when we put aside all our daily work, trusting in the Lord to meet all our needs, and just come apart and spend the whole day with HIM.

I don't think Rick is worried about people meeting together for prayer meetings and Bible study during the week. He is worried about setting apart Sunday and acting as if it were the Sabbath God blessed and hallowed.

Christ kept the seventh day Sabbath. It was His custom to attend the synagogue on Sabbath. and I'm pretty sure His carpenter's shop was closed every Sabbath.
Christ viewed the Sabbath as a day of restoration spiritual and physical. Rules that conflicted with the meaning of the Sabbath, Christ discarded -- but Christ kept God's law PERFECTLY.

Just a quick update, yesterday in Sabbath School one of the members from our old church came up and related something that left me very sad. He stated that the leaders of our old church called him, and ask him to come as Santa Claus for their church service. He told me he couldn't even bring himself to try to explain to them how wrong this was, and told me this is the 'third year' in a row they have asked him to do it. I didn't know what to say.....

For the leaders to be leading the congregation astray, that is an apostasy of the most startling nature

Well, I just found yesterday that it has spread into the Spanish Adventist church, nearby, and much like ours the first elder and others were shown the exit door. And they had just finished buying the building for the church and the property not long ago. I will update once I know more..

There is more ahead: The RCC male priesthood model is being embraced by the GC. And our stand on abortion that was settled over 50 years ago is being tweaked to align more closely with the RCC position. Positions that have withstood time are being chipped away by our leaders (oh no say it ain't so) and apostacy of a most startling nature is already here.

That is a bit of stretch as it was a change that was turned down, not a shift.
