And there goes the Caucus Designation.
There is truth to the previous statement. The Lambeth Conference, held in 1930, by the Anglican communion, specifically spoke to, and allowed contraception:
Marriage and Sex: Resolutions 9-20
Resolution 15 allowed “in those cases where there is such a clearly felt moral obligation to limit or avoid parenthood, and where there is a morally sound reason for avoiding complete abstinence, the Conference agrees that other methods may be used, provided that this is done in the light of the same Christian principles.” The vote for this Resolution was 193 for it, 67 against it, and 47 not voting. This was the only Resolution for which a record of the numbers voting was required.[23]
The London Times of June 30, 1930, predicted that the Lambeth Conference would change the “social and moral life” of humanity. This was done by the Conference’s Resolution 15 in which in contradiction to earlier Resolutions (1908 Resolution 41 and 1920 Resolution 66) allowed the use of contraception in marriage.[24]
William Carey, Bishop of Bloemfontein, withdrew from the Conference in protest and even sent a petition to the King on the subject.[25]
