ASAP :) What can you infer about Friar Laurence from the line in bold?

JULIET
Tell me not, friar, that thou hear'st of this,
Unless thou tell me how I may prevent it:
If, in thy wisdom, thou canst give no help,
Do thou but call my resolution wise,
And with this knife I'll help it presently.
God join'd my heart and Romeo's, thou our hands;
And ere this hand, by thee to Romeo seal'd,
Shall be the label to another deed,
Or my true heart with treacherous revolt
Turn to another, this shall slay them both:
Therefore, out of thy long-experienced time,
Give me some present counsel, or, behold,
'Twixt my extremes and me this bloody knife
Shall play the umpire, arbitrating that
Which the commission of thy years and art
Could to no issue of true honour bring.
Be not so long to speak; I long to die,
If what thou speak'st speak not of remedy.

Bolded lines: Which the commission of thy years and art
Could to no issue of true honor bring.

Friar Laurence has been the holy man in that town for many years.
Friar Laurence is very young and inexperienced as a holy man in Verona.
Friar Laurence is not someone Juliet believes she can trust with secrets.
Friar Laurence is someone who is known to regularly make mistakes.
