Pete encourages us to keep to the simplicity of the Christian message, spelt out in Mark12, verses 28-34.
The Greatest Commandment
28 One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, "Of all the commandments, which is the most important?" 29 "The most important one," answered Jesus, "is this: 'Hear, O Israel: The Lord our God, the Lord is one. 30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.' 31 The second is this: 'Love your neighbour as yourself.' There is no commandment greater than these." 32 "Well said, teacher," the man replied. "You are right in saying that God is one and there is no other but him. 33 To love him with all your heart, with all your understanding and with all your strength, and to love your neighbour as yourself is more important than all burnt offerings and sacrifices." 34 When Jesus saw that he had answered wisely, he said to him, "You are not far from the kingdom of God." And from then on no one dared ask him any more questions
