In the analysis of Vern Rossman, the Movement's fraternal delegate to the IVCF missions conference of 1951, there were four barriers to cooperation between the IVCF and the SVM: l)historical: the IVCF's reaction against the general student movements" humanitarian drift of the 1930s and its desire for institutional preservation; 2) psychological: the IVCF's taboos on smoking, dancing, and cosmetics, its particular forms of religious jargon, its inclination toward political and economic conservatism; 3) theological differences; and 4) the IVCF's lack of ecumenical spirit, "IVCF sees itself as exclusive in function ... doctrinally pure, true to the Bible ... emphasizing holiness almost to the exclusion of catholicity." Rossman reported that the IVCF conference program stressed Bible study and worship and although a few unofficial representatives of mainline denomination missions boards attended, the platform speakers generally represented conservative or faith missions boards.
