#1 in the confessions you provided.
- We believe, teach, and confess that the sole rule and standard according to which all dogmas together with [all] teachers should be estimated and judged are the prophetic and apostolic Scriptures of the Old and of the New Testament alone, as it is written Ps. 119:105: Thy Word is a lamp unto my feet and a light unto my path. And St. Paul: Though an angel from heaven preach any other gospel unto you, let him be accursed, Gal. 1:8.
The teachers they are talking about are the Church. Priests, etc. but even that phrase limits personal interpretation.
To what? Look at Lutheranism.
B. Ending a Pregnancy
This church recognizes that there can be sound reasons for ending a pregnancy through induced abortion
“This church supports the development and use of medical products, birth control, and initiatives that support fulfilling and responsible sexuality. This church also recognizes the important role that the availability of birth control has played in allowing women and men to make responsible decisions about the bearing and rearing of children.” (A Social Statement on Human Sexuality, 2009 page 35) 
Lutherans approve of same sex marriage.
Well, not all Lutherans. But all Lutherans, according to you, view the Scripture through the lens of the confessions, as taught by the church.
