Christianity and Wicca are two rather different religions (each with different denominations). Together the words themselves are an oxymoron.
What you are discussing are those who worship the triad as many would worship the Maiden, Mother, and Crone, or some other similar trinity.
Often they do call themselves "Christian Wiccans" due to a lack of understanding of how words work together, or the history of either faith.
And many Yoruba-based traditions do deify the Saints, but they often worship saints that represent a particular Yoruba god/goddess/spirit. Thus the Orisha/saints. But this isn't strictly Christianity. This is Santeria, and similar such faiths, that have been influenced by Christianity.
Christianity reveres the "one god", the holy spirit, and the son (Jesus). The saints are not strictly worshipped but often praised as those who have come close to god and can guide you through trials or what have you. However, many forms of Christianity do not focus on the saints and instead labor to seek closeness with God.
Generally speaking, in my opinion, the whole saintly system seems to cater to the root pagan cultures' need to associate different entities with different aspects instead of seeking all answers from one source, ie God.
As to your goal, Anastasia, if you are seeking peace within your spirit and seek to do so through the Christian God, pray to him. Seek oneness, and a life without sin, and so forth. Cling to the commandments and live your life as a good christian. Healing comes with time.
