Sorry, not a Saint.
God decides who is a saint. Not you or anyone on earth.
You mean not a Roman Catholic Saint, but he IS a saint who is beholding the face of our Lord and Savior Jesus Christ. All the sanctified in Christ are saints through faith because of the grace of God and one day we will meet brother Martin in heaven. Who knows, Salvation, maybe you'll be there too!
Sorry you are unfamiliar with Scripture:
...the word "saint" is used more generally to refer to anyone who is a Christian. This is similar in usage to Paul's numerous references in the New Testament of the Bible.[44] In this sense, anyone who is within the Body of Christ (i.e., a professing Christian) is a 'saint' because of their relationship with Christ Jesus.
