Here is an email which I wrote(in part) the rest is taken from an excellent apologetics site, which I dont have off hand unfortunately.
Greetings *Pastor *
In discussion with a Roman Catholic priest , I noticed that you did not refer to him as father. This annoyed me. I thought the old “call no man father” argument, was dead, but it seems it is alive and well.
From a study of the entire body of revealed scripture, I hope to demonstrate to you that it is entirely scriptural to call a Priest, father.
Ephesians 6:2-4: “‘Honour your father and mother that it may be well with you and that you may live long on the earth. Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord.’ Wouldn’t you say your father is someone on this earth? But Jesus said ‘call no man your father on earth.’ Jesus did not say ‘call no man father on earth except your biological father.’ Is this a contradiction?" you ask.
You may say that clearly, in Matthew 23, Jesus is speaking in the context of calling religious leaders ‘father.’ "
"So you’re saying that when Jesus said ‘call no man your father on earth,’ He didn’t mean that in an absolute and all-encompassing way? We have an exception when it comes to our biological fathers.
Listen to the very words of Our Lord in Luke 16:24: ‘And he [the rich man] called out, Father Abraham, have mercy upon me, and send Lazarus to dip the end of his finger in water and cool my tongue; for I am in anguish in this flame.’ Would you say Abraham is a religious leader, Pastor?"
“Not only does Jesus refer to Abraham as ‘father,’ but St. James does likewise in James 2:21, as does St. Paul, calling Abraham ‘father’ seven times in Romans 4:1-18. Are we to believe Jesus, St. James and St. Paul are contradicting Matthew 23:9?”
Perhaps you will try to salvage this by saying, it’s okay to refer to someone who has gone before us in the faith as ‘father.’ They are our ‘fathers’ in the faith. But this is a far cry from giving our living leaders today the title of ‘father,’ which, according to Matthew 23:9, is reserved to God alone."
But it is possible to demonstrate to you it is in fact Biblical to call our living spiritual leaders ‘father’?
Twice in 1 John 2:13-14, St. John calls the leaders of the Church to which he is writing ‘fathers’: ‘I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I write to you, children, because you know the Father. I write to you, fathers, because you know him who is from the beginning.’
In Acts 7:1-2, St. Stephen, under the inspiration of the Holy Spirit as shown in Acts 7:55, calls both Abraham and the elders of Jerusalem ‘father’: 'And the high priest said, “Is this so?” And Stephen said: 'Brethren and fathers, hear me. The God of glory appeared to our father Abraham.
And in 1 Corinthians 4:14-15, St. Paul refers to himself as ‘father’: ‘I do not write this to make you ashamed, but to admonish you as my beloved children. For though you have countless guides in Christ, you do not have many fathers. For I became your father in Christ Jesus through the gospel.’ Time does not allow me to quote to you 1 Thessalonians 2:11, John 4:12, Acts 4:25 and Romans 9:10. All of these verses refer to men, whether alive at the time or not, as ‘father.’
