There are no problems at all...If a theology can't use all the scriptures there's something wrong with the theology...That's why your catechism won't touch those scriptures in Corinthians...
A theology that twists itself into knots to say “What God hath joined together let no man set apart” is consistent with “Art thou loosed from a wife? seek not a wife. But and if thou marry, thou hast not sinned; “ is a Theology of the White Queen, who boasts she can “believe six impossible things before breakfast”.
