Jesus never said to attend Church on Sundays.
Jesus never told us to celebrate Christmas or Easter.
Jesus never told us to have raffles.
The Scriptures do not record a great deal. The Scriptures say next to nothing about actual worship.
Does our salvation depend on whether we follow those things you mention?
** Mark 11**
15On reaching Jerusalem, Jesus entered the temple area and began driving out those who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves, 16and would not allow anyone to carry merchandise through the temple courts. 17And as he taught them, he said, “Is it not written:
" ‘My house will be called
a house of prayer for all nations’? But you have made it ‘a den of robbers.’”
These say a great deal about how we are to worship:
Matthew 15
1Then some Pharisees and teachers of the law came to Jesus from Jerusalem and asked, 2"Why do your disciples break the tradition of the elders? They don’t wash their hands before they eat!"
3Jesus replied, “And why do you break the command of God for the sake of your tradition? 4For God said, ‘Honor your father and mother’ and ‘Anyone who curses his father or mother must be put to death.’ 5But you say that if a man says to his father or mother, ‘Whatever help you might otherwise have received from me is a gift devoted to God,’ 6he is not to ‘honor his father’ with it. Thus you nullify the word of God for the sake of your tradition. 7You hypocrites! Isaiah was right when he prophesied about you:
8” 'These people honor me with their lips,
but their hearts are far from me.
9They worship me in vain;
their teachings are but rules taught by men.
.
Acts 20
7On the first day of the week we came together to break bread. Paul spoke to the people and, because he intended to leave the next day, kept on talking until midnight.
Acts 2
42They devoted themselves to the apostles’ teaching and to the fellowship, to the breaking of bread and to prayer.
Ephesians 5
19Speak to one another with psalms, hymns and spiritual songs. Sing and make music in your heart to the Lord
2 Timothy 4
2Preach the Word; be prepared in season and out of season; correct, rebuke and encourage—with great patience and careful instruction. 3For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. 4They will turn their ears away from the truth and turn aside to myths. 5But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry.
