Simply by his name, for example: Mr. John Smith.
Jesus said: "But YOU, do not YOU be called Rabbi, for one is YOUR teacher, whereas all YOU are brothers. Moreover, do not call anyone YOUR father on earth, for one is YOUR Father, the heavenly One. Neither be called 'leaders,' for YOUR Leader is one, the Christ. But the greatest one among YOU must be YOUR minister. Whoever exalts himself will be humbled, and whoever humbles himself will be exalted." [Matthew 23:8-12]
Hence, it is inappropriate to address any person using a religious title that would place him/her in a role only rightly held by our creator, Jehovah God.
I would ignore the above. Actually if you call someone Mr, you are calling them "Master"! The passage of scripture also says call no one your Teacher - but we do.
The way to address them in speech is "Father X", on an envelope "The Revd XX" if they are a priest.
Of course the most polite way to address someone is how THEY wish to be addressed and not how some biblical fundamentalist thinks they should be addressed.
In the Lutheran Church, a vicar is a seminary student who is completing a year of practical fieldwork in a congregation, typically as part of their pastoral training. This role allows the vicar to gain hands-on experience in ministry under the supervision of an experienced pastor. The vicar may perform various duties, including preaching, teaching, and participating in church activities, but is not yet ordained. This internship period helps prepare them for their future role as a fully ordained pastor.
