You know I have been thinking of the baptism of Simon Magus. From Acts 9:13 "Even Simon (Magus) himself believed, and after being baptized he continued with Philip." Also from Acts 9:18-21 "...when Simon saw that the Spirit was given through the laying on of the apostles hands, he offered them money. Saying give me this power also, so that anyone whom I lay my hands may receive the Holy Spirit. But Peter said to him...You have neither part nor lot in this matter for your heart is not right before God."No you're fine you can stay here. I am a Unitarian and even though everyone is always challenging me, I don't mind. I actually enjoy talking about it. Regardless of the disagreements, it does press me to keep looking and digging, yet I am quite content.
So obviously baptism does not necessarily lead to the gift of the Holy Spirit. More is required.
