David Instone-Brewer, a Baptist Minister working in the academic world at Tyndale House, Cambridge, UK, who writes articles in ‘Premier Christianity’ magazine in March 2019 that:
“part of becoming a Christian … depend[s] on having a minimum set of core beliefs” The first of which is that “if you are going to have faith in God, you at least need to accept that he exists.”
Starting from that what else do you need to accept?
Instone-Brewer looks at what is said in the Bible, especially the sermons preached in the book called the Acts of the Apostles, a book describing the life of the early church and of the new believers who came to trust in Christ Jesus. From these he suggests three core beliefs that you must hold to be a Christian:
 Believe in God the Holy Trinity.
Jesus is ‘Lord of all’, for He “is named with God and the Spirit” [as stated in the part of the Bible referred to as Acts Chapter 10 verses 36-38,] in which Peter speaks to Cornelius saying:
“You know the message God sent to the people of Israel, announcing the good news of peace through Jesus Christ, who is Lord of all. You know what has happened throughout the province of Judea, beginning in Galilee after the baptism that John preached – how God anointed Jesus of Nazareth with the Holy Spirit and power, and how He went around doing good and healing all who were under the power of the devil, because God was with Him.” [NIV]
 Believe in Jesus’ death and resurrection, as Peter went on to say to Cornelius
“We are witnesses of everything He did in the country of the Jews and in Jerusalem. They killed Him by hanging Him on a cross, but God raised him from the dead on the third day and caused him to be seen. He was not seen by all the people, but by witnesses whom God had already chosen – by us who ate and drank with him after he rose from the dead.”
 Believe in forgiveness by faith in Jesus, as Peter further said:
“Jesus …commanded us to preach to the people and to testify that He is the one whom God appointed as judge of the living and the dead. All the prophets testify about Him that everyone who believes in Him receives forgiveness of sins through His name.”
Coming to faith is an act of God’s grace which leads believers to repent and be baptised, and in that you can see how these core beliefs interlink, for as Instone-Brewer notes:
“Before you can repent, you need to know about sin and judgement – and the hope of forgiveness. And before you trust Jesus and get baptised in his name, you need to know why he is special.”
