Inspired by speakers such as Irvine and Cooney, membership growth was rapid. Rather than adding members to established denominations, as was the practice of the Faith Mission outreach, churches began noticing their congregations thinning after exposure to the Two by Two missions. Clerics soon began regarding the Two by Two preachers as "inimical to the membership of the church". After receiving reports from Ireland, the Faith Mission in 1900 formally disassociated itself from Irvine and any of its workers found to be participating in the new Two by Two movement.
