I remember reading a webpage about the issue of calling someone father. One of the points made against the practice was an Old Testament passage of someone asking another person to be his father spiritually.
As Wikis noted, Matthew 23 is the passage to which the person was probably referring:
The idea is that men should not be exalted over us in such roles. The religious rabbis and teachers of the law were the most corrupt and dishonorable to God. Jesus commands us to not seek such titles for ourselves, nor give them to others, but to exalt God as Father and Teacher and Master.
