large portions of the Book of Concord which is our Confession. A Confession that defines what it means to be 'Lutheran'. So, if we submit ourselves to the Book of Concord and its teaching, Luther would be right there with us.
Luther called those who deny Infant Baptism heretical fanatics. I have his Large Catechism right here. Doubt me, look it up yourself.
Those who deny the Real Presence in the Lord's Supper are also called fanatics who do not know scripture. Luther set himself against those who denied the sacraments very, very vehemently. So much so, that it will probably hurt your feelings.
Yes, Luther would be against the ELCA which denies the Book of Concord and is in communion with various reformed churches. So, if you are talking about that yes. Luther would probably be hanging out with the LCMS at this point as we are Confessional Lutherans.
Our enemies called us Lutherans. Many of our churches are called 'Evangelical' for this very reason that Luther wanted the Church named the Evangelical Church, or the Church of the Good News or the Church of the Gospel.
May the LORD bless you and keep you
May the LORD make His face shed light upon you and be gracious unto you
May the LORD lift up His face unto you and give you peace
