Here are some points to consider concerning how we welcome a new pastor and treat him after he’s been with us a while: 
DON’T PUT TRADITIONS ABOVE RELATIONSHIP:  There should be no sacred cows we hold onto.
DON’T EXPECT A TRANSFORMATION OVERNIGHT:  A new pastor needs time to adjust to our culture, traditions, history.  He needs to find his own path.
GIVE HIM SOME SLACK:  Allow him to make mistakes.  Let him test the waters.  It’s okay to experiment and try new things.  That’s why we hired him. 
COMMIT TO PRAY FOR HIM AND HIS FAMILY: They’re in a new situation – a strange town – facing new challenges like finding doctors, shopping, health insurance, registering their car – finding his role in the community and with his fellow pastors. 
DON’T TALK TOO MUCH ABOUT PREVIOUS PASTORS: Give him a chance to develop his own legacy without being in someone else’s shadow. 
PRAY SPECIFICALLY FOR PROTECTION: The devil’s not happy about having a “new sheriff” in town. 
ALWAYS BE LOVING AND HOSPITABLE: When the newness wears off, we should still show him and his family our appreciation by word and deed.
SUPPORT HIM FINANCIALLY: the workman is worthy of his hire. 
PROTECT OUR PASTOR: Don’t let gossip or a bad report take hold.  Treat him in a loving, open-minded way.  “Love thinks no evil, rejoices  not in iniquity, and bears all things.” 1 Corinthians 13.  And if there’s an issue, try to resolve one-on-one.  Follow the admonition in Matthew 18:15-17.  
GIVE HIS WIFE TIME TO DETERMINE HER ROLE:  Let’s not put expectations on her but see how God reveals the ministry she is to follow. 
DON’T PUT UNDUE EXPECTATIONS ON HIS CHILDREN: We shouldn’t expect anything more of them than we do of our own children. 
WE NEED TO REMEMBER OUR ROLE AS WELL AS THE PASTOR’S: We’re in this boat together.  (Ephesians 4:12-14).
