Vertical, horizontal

A regenerate Christian can't but have some - some - sympathy for elements of the Radical Reformation. All one can say is 'some' elements due to the fact that it didn't have any central, dogmatic belief or confession, and it's wiser leaders tended to be targeted first for annihilation by more establishment Protestants, and also Roman Catholics of course. The four ancient attributes of the church: unity, holiness, universality, apostolicity...they all exist in the new heart of a believer, in connection with Jesus Christ via the Holy Spirit, and through Jesus to God the Father.

To find these attributes in Christianity, in being a Christian, you have to look vertically to God, not horizontally to society or other Christians. The unity and universality of the faith exists in one's regenerated heart, and the connection with God is internal and vertical.

You will get persecution (or at least friction) from the world, from other humans, including Christians. You meet that with love. That is part of the doing of the faith. It effects sanctification. Love God, love your neighbor as yourself. Love your enemy.
