The Methodist Church preaches the Gospel through the eyes of John Wesley.
No; the Methodist church preaches the Gospel as laid down in Scripture.
The Gospel being that mankind sinned, rebelled against God and deserved eternal death, or separation from God, but that God didn't want that for us. He loved us so much that he wanted to reconcile us to himself - which he did, through Jesus and the cross.
Grace alone and Faith alone are wrong and not Scriptural.
Grace alone and faith alone are not the Gospel.
The Gospel is Jesus - both God and man, born, live, died, raised to life, ascended, who sent his Spirit to live in his followers so that they might live for him, and who will return one day in glory.
Jesus said that whoever believes in him has eternal life, John 3:16, John 3:36; it is the work of God that we believe in Jesus, John 6:29, and the will of God that we come to him to receive eternal life, John 6:40.
Jesus is the Lamb of God who takes away the sin of the world, John 1:29, 1 Peter 1:19-20. He said himself that he came to give his life as a ransom for many, Mark 10:45, that he is the Good Shepherd who would lay down his life for the sheep, John 10:11, John 10:15, that his blood would be shed for the forgiveness of sins, Matthew 26:28. He said that he is the only Way to the Father, John 14:6, and Peter said that he is the only Saviour, Acts of the Apostles 4:12. Jesus died to reconcile us to God, Romans 5:11, 2 Corinthians 5:18 and through him we have peace with God, Romans 5:1.
Having been crucified, Jesus was later raised from the dead. He was raised a) because he was God and the tomb could not hold him and b) God wanted everyone to know that he was who he had claimed to be, Romans 1:4-5.
Everyone who believes in Jesus, believes and accepts who he was and what he taught and died for, has eternal life. Jesus came that we should have life, John 10:10; eternal life is the work, will and gift of God, Romans 6:23 and is available to everyone, 2 Peter 3:9.
If someone accepts Jesus, believes in him, receives eternal life but then dies - 5 weeks, days, hours or minutes later; they will have died with Christ and eternal life.
That is the Gospel.
In your burger analogy, that is the burger. The relish is the church practices - baptism at a certain age, ordaining/not ordaining women, speaking in tongues, dancing in the aisles, prophesying, using incense, praying to the saints, tithing/ or not.
Both literally and metaphorically, I hate relish. It doesn't taste nice (except for a bit of cheese occasionally) and spoils the taste of the burger. In fact sometimes it seems that there is so much relish that the burger can't be seen.
Just as in the church.
You say you follow the Gospel as taught by Wesley, but you don't have to agree with all he taught.
No, I don't have to agree with all he taught - and if he hadn't taught the Gospel, I wouldn't agree with that either.
You seem to have missed the bit of my post where I said that I heard the Gospel and became a Christian long before I joined the Methodist church.
But Wesley is a man who came along 1500 or so years after Christ. So you agree with some of what he taught, which is fine, but no two people can believe the same body of what Wesley taught, so how many denominations of Methodism are there???
It makes no difference how many denominations there are - there is ONE Gospel and ONE Saviour.
