Galatians 3:1-5 / Luke 11:5-13
In forensic psychiatry there are two major areas of criminal evaluations. These are Competency to Stand trial (CST) and Mental State at the Time of the Offence (MSO).
Forensic psychiatrists work with courts evaluating an individual's competency to stand trial, defenses based on mental diseases or defects (e.g., the "insanity" defense), and sentencing recommendations.
Putting it simply, although it may be over-simplifying things, the forensic psychiatrists determine whether those on trial are mad or bad.
In the opening lines of the 1st reading, St. Paul seemed to be asking the Galatians if they were mad or bad.
Because they are turned away so quickly from the truth of the gospel and entertained other forms of practices and teachings that St. Paul had to ask if they were mad or if they were under some kind of spell.
Furthermore it was because they had believed in the truth of the gospel and hence they received the Holy Spirit. But now they turned to other teachings and practices thinking they could get more of the power of the Holy Spirit.
Indeed the simple and profound truth of gospel is that Jesus was crucified and died for our sins to save us. Believing in that would open us to live our lives in the Spirit.
And if we live our lives in the Spirit, then what Jesus said in the gospel would certainly be true : Ask and it will be given to you; search and you will find; knock and it will be opened to you.
We just need to persevere and persist in believing the truth and to believe that the Holy Spirit would lead us along the way.
Believing in something else may mean that we are either mad or really bad.
