Roman Catholic Christians have a long custom--tradition--to address their priests as "father." Many Christians feel that this practice is in disagreement with the word of God.
Mt 23:8-10 As for you, do not be called 'Rabbi.' You have but one teacher, and you are all brothers. Call no one on earth your father; you have but one Father in heaven. Do not be called 'Master'; you have but one master, the Messiah.
If this passage was meant to be taken literally, then we all offend the Scripture. We all have used "father" to designate our birth father; and "teacher," our instructors at school. On the other hand, the meaning of the scripture is that no person should be given the respect and honor due ultimately to God the Father.
Catholic Christians call the priests "father" with the sense understood by Paul.
1 Cor 4:14-16 I am writing you this not to shame you, but to admonish you as my beloved children. Even if you should have countless guides to Christ, yet you do not have many fathers, for I became your father in Christ Jesus through the gospel. Therefore, I urge you, be imitators of me.
1 Thess 2:11-12 As you know, we treated each one of you as a father treats his children, exhorting and encouraging you and insisting that you conduct yourselves as worthy of the God who calls you into his kingdom and glory.
