The problem in focus for this study is ?Understanding the Eucharist among Anglicans, Baptists and Catholics,: Implication for Christian unity?, was set against the background of certain constraints on the emphasis by Anglican, Baptist and Catholic Churches of those considered as worthy participants in the Eucharist this implies that not all Christians are illegible to participate. In carrying out this study four objectives were formulated. They are: find out if there is common understanding of Eucharist among Catholic, Anglican and Baptist Clergy. Find out the understanding of Eucharist among Catholics, Anglican and Baptist members, to determine the implications of Eucharist for Christian unity among Catholic, Anglican and Baptist clergy, and to ascertain if Eucharist is a factor for Christian unity among Catholic, Anglican and Baptist members. Four research questions and null hypotheses respectively were set and tested at 0.05 levels of significance. A survey research method was adopted in this study and the population for the study comprised of 2,359,481 Anglicans, Baptists and Catholics with interest on only communicants from these denominations. A proportional random sampling technique was used to obtain the number of respondents from the sample size of 600 from three senatorial zones of Kaduna State. A structured questionnaire which was divided into two parts was divided into two parts the first part seeks to identify the understanding of the Eucharist, and the second part was to identify the implication of the Eucharist on Christian unity. Six hundred copies of the questionnaire were distributed to the respondents. Five hundred and five were dully filled and returned. Descriptive data analysis was adopted using simple percentage, mean, and one-way analysis of variance (ANOVA). A significant difference was observed on the understanding of Eucharist viii among the clergy and members of the three denominations. While there was no significance observed on the implications for the Eucharist among Catholic, Anglican and Baptist clergy. However, there was significant difference on the implications of the Eucharist among members of the three denominations. Based on the findings from this study, the following conclusions were made: The level of understanding of Anglican clergy on the Eucharist is similar to that of Catholics but slightly differ from Baptist. The emphasis on worthiness of communicants of the Eucharist is to prevent a host of risks of bringing condemnation but some members feel marginalized by the act. Catholic members have understanding of their church teaching on the Eucharist. Anglican and Baptist members feel marginalized by Catholics refusal to let them partake in the Catholic Eucharist. Based on the findings the following recommendations were made. The Anglican clergy should revisit their common prayer book for proper understanding of the Eucharist, because their level of understanding differs with their church teaching. Catholics, Anglican and Baptist clergy should an initiate inter-denominational dialogue on who is worthy to partake in the Eucharist, and define the yardstick for measuring a person's worthiness or unworthiness. Catholic members should be encouraged to explain to Anglican and Baptist members that are interested in their Eucharist why it is restricted to them, and how they will go about it if they want to partake in it. Anglican and Baptist members should not feel bad if Catholics do not allow them to partake in their Eucharist because every church has its own teachings on the Eucharist, but that of Catholics differ with theirs. Unity in diversity should be welcome by all Christians.
